Phenotype: The part of the hamster we can see (colour, pattern, fur type, etc), Genotype: The genotype is presented by the genetic code, and tells us the information about the hamsters genetics, both seen and unseen, Allele: The genotype is made up by pairs of alleles, Locus: Each pair of alleles belongs to a locus, the locus is represented by a letter symbol, or, since there are two alleles, two letters, Dominant: The hamster only needs one copy of the gene to show. For a Syrian Hamster, you need a large hamster cage with a floor space of at least 360 square inches (3012 inches) (2,300 square centimeters) and a total area of 2 cubic feet (55 liters). These are called recessive genes/ alleles. I set up this site on [] in order to create a nice place where people could come, learn about Hamster genetics, learn the correct names and gene codes for a Hamsters' Colours and also to record Genetic Abnormalities in Hamsters, such as Chimerism and Mosaicism. As a guide to selecting, here is an excerpt from the British Hamster Association Exhibition Standards. Some have been standardized by clubs for show purposes. Normal adult gerbils and Syrian hamsters require about the same levels of protein, fats and fibre (12%, 6-8% and 4-6%) which are found in most store-bought products - as well as a sprinkling of fresh fruit and vegetables a few times a week from a species-relevant fresh food safe list. The situation often arises in pet shop litters where a group of hamsters is known to be from the same litter, but information on the parents is unavailable. People who want Syrian hamsters will seek out the best breeders to find their next critter. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Recessive genes, inherited in the same way as has been described for Cinnamon, include; dark grey, cream, dark eared white, black, rust, ruby eyed fawn, piebald, rex and longhair. To write out the complete genotype of a Golden hamster carrying no mutant genes, every one of the many thousands of genes would need to be identified, issued a symbol and compiled in an exhaustive list. Sometimes, the offspring answer questions that were not even asked. Do not disturb her while she works. the effect of a gene by a nonallelic gene. Rusts, the three Greys, Cinnamons, Yellows, Extreme Dilutes and, of course, Goldens all have agouti markings. Females get one yellow (or non-yellow) gene from each parent. This generation from the first crossing are called the First Filial generation, (F1). The ears of most Syrians are various shades of grey, deepening to black in Black hamsters. female hamsters in general are larger than males. Mottled ears, where pale patches are mixed with grey, can occur in conjunction with any white pattern gene except Recessive Dappled. Syrian Hamster Genetics: Principles of Breeding. Rust first appeared in 1960 and was described by Roy Robinson. rxrx, https://hathorhamstery.weebly.com/basic-genes.html, Scan this QR code to download the app now. ee, A lighter grey hamster with a very slight creamy undertone, is homozygous lethal so all hamsters with two copies of the gene will be absorbed in utero. Dark Grey will not appear in thefirst generation; Light and Silver Greys will. Depigmented ears are part of the Cinnamon phenotype, alone or incombination with other colors. For a dominant mutation like Silver Grey the situation is reversed; the mutant allele, (Sg), is dominant and the wild type recessive, (sg). You will also have a good idea of what the Syrian hamsters pups will look like. Also, the white areas can overwhelm the yellow to the point where none are visible. They have a wild type gene at the Cinnamon locus and so show do not show the effect of the Cinnamon allele, p. In the same way, they do not show the effect of the Dark Grey allele, dg. Here we use a comparative genomic approach to generate a molecular genetic map of the Syrian hamster X chromosome that includes Sex-linked yellow, which provides a basis for molecular genetic and epistasis studies revealing that Sly represents a component of the melanocortin pathway similar to, but independent of, the Mc1r. If its wet and soiled, then replace the bedding and nesting material. Please email or text 570-573-4597 with any questions! Your hamster will most likely give birth at night. Different patterns. matter what color it was supposed to be. Examples are cousin Others have lost the special hue and tone characteristic of the pure color sought for on the show bench. It basically 'cloaks' the original colour. When you purchase Syrian hamsters from a pet store, you have no idea how old they are, or what their parents look like. Also, the hairs of the fur have bands of different color, usually lighter in the middle section. These Syrian hamsters are not documented, and their genetics are not controlled. This will familiarize the hamsters to their different smells. This gene is dominant - so you only need 1 of these to see the effect - and it is also dominant physically over the normal and the sapphire coat colors. Never handle your hamster when it is near the due date. They are part of the rodent family which takes up 40% of the mammalian orders. Information gathered from siblings is less definitive, but still can be helpful. Syrians are born with their eyes closed and the only time they open is when they're between twelve and fourteen days old. They will often have a white chin and paws. Syrian Hamster Genetics On our Instagram page, I've started a series of genetics posts that (hopefully) teach Syrian hamster genetics in an way that is easily understood by everyone, even without a background in genetics or biology. If the genes are there, with a little luck and time you should be able to produce quality hamsters with any combination of This can only happen in XX animals, (i.e., females), and is called Tortoiseshell. They are omnivores and eat a variety of things, including fruits, vegetables, seeds, nuts, and . Validated Species: Human. Native to Syria and Turkey, wild Syrian hamsters are a golden brown color with cream or white undersides. Agouti: The hamster will have agouti markings including dark eye rings, head splotch, cheek flashes, and lighter underside. share the parental phenotype. ("_" stands for "unknown."). Syrian Hamster Appearance How Big do Syrian Hamsters Get? Condition (10 points) Recessive genes are represented by lower case letters. The eyes shall be large, prominent and widely set. Yellow often appears like golden but the main coat is lighter. Prepare a neutral territory. In the heterozygous form they will often have a creamy hue. The male, however, has wild type alleles, (Dg), at his Dark Grey locus and his mate has wild type alleles at her Cinnamon locus. Although it cannot be seen, the Cinnamon allele, (p), is in the makeup of these hamsters, inherited from their father. Campbell's Dwarf Hamster- 2 years. The height gives your furry friend the option to burrow and make tunnels. The second breeding technique, crossing, is the pairing of the selected individuals so that the best offspring possible can be produced. They make a great pet to teach your child about responsibility. The new study uses Syrian hamster models of moderate COVID-19 disease to better understand systemic and lung cellular responses and match these to severity outcomes in datasets from COVID-19 patients. Hamsters without these features are called Self-colored hamsters, or Selfs. Along the length of each chromosome are loci for the various genes on that chromosome. generation. dd Dark grey A dark grey hamster with very dark or black agouti markings. If a pure breeding Cinnamon male is mated to a pure breeding Dark Grey female, the resulting litter are all goldens. Genetics, as well as the care and stress levels play a big role in how long and how well your hamster lives. They carry BOTH Cinnamon AND Dark Grey. Chinese Hamster- 1.5-2 years. Also, the ratios of each colour expected are just that; the ratios expected. Fur (20 points) Whereas Tortoiseshells often do not have distinct patching, Tricolors more often do. Have two enclosures ready to go and place the males in one and the females in the other. If an egg is fertilised by an X bearing sperm an XX female results. With the probablity formula we discover that there is actually about a 66% chance that there will be at least one Black Tort in the average Syrian litter of 8. The male will produce sperm with the genetic makeup p Dg, (considering the alleles at both gene loci). The Syrian or golden hamster ( Mesocricetus auratus) originated in Syria and naturally resides in the arid, temperate regions of southeast Europe and Asia Minor. degree relatives. This is the colour that hamsters come in the wild, and isnt a mutation as it is the default colour. Look at the distance between each hamsters anus and genital opening. Besides the typical golden brown color, it has agouti markings - cheekflashes, crescents, a chestband and a light colored underside. Allowance shall be made for sex; i.e. No difference was observed using either cardiac or We screened a Syrian hamster genomic DNA phage library skeletal muscle cDNA templates. This means that, if an animal has a yellow, (To), and a wild type, non Yellow, (to), allele at the Yellow locus, it will show both. Older hamsters that breed will produce fewer babies and the pups will have various genetic problems. We obtained the same data using the -SG cDNA as a probe. Mutations at a gene locus may cause something to be altered in the development of the characteristics controlled by that gene. the gene in winter whites that determines whether the hamster is white or mainly white in color. Any combination color that incorporates one or more the the self colors will also be Self. The Golden hamster will have two wild type alleles, (PP). (yellow + black) So, in a female, you usually get torts, and in males you (always) get plain yellows, or these combination colors.A yellow female, when bred with a non-yellow male, will produce, stastically, 50% yellow males, and 50% yellow females. When the Golden female makes eggs she will send one chromosome of each pair to each egg. Patterns may be added, but the color is solid, with no cheek flashes. By a similar deduction, all the Cinnamon males sperm cells will contain only the allele p. When these gametes fuse to form an embryo hamster the genetic makeup that it will inherit is Pp. the original Yellow male. So I'm considering trying to make a syrian hamster genetics calculatorInspired by the chinchilla one I saw on another thread on the forum. Spread the litter evenly throughout the enclosure. All pictures are my own. You do not want to stress the momma hamster, but you still need to be sure she has everything she needs. Shows the probabilities for each outcome. Location: Yorkshire, UK but my heart lies in Scotland! standards, outcrossing is a good way to maintain the production of vigorous animals. This is the end of the genetics tutorial. The litter is then three fourths as large as it would have been and has the remaining genotype (and phenotype) ratio of 2:1. Business, Economics, and Finance. The Syrian Hamster is the most common and is the largest of the 20 species of hamsters. Always scoop them with both hands gently when picking them up and stroke them very gently (avoiding the nose and whiskers). Others show their effect even if the hamster has only one copy, (i.e. (The eleventh is the Umbrous gene. Some Syrian hamsters have been recorded to grow to 30cm long, even though the average size comes to about 20cm. The Syrian hamster is the second-longest lived hamster, right after the Roborovski Dwarf. Other coat colours created by combining two or more genes include; So far we have only looked at alleles that can be inherited from either parent. Female Syrian hamsters will begin to show signs of pregnancy about two days before the birth. Clean out your female hamster's cage. Red-Eyed Cream Red-eyed cream is simply cream with the cinnamon gene added. Since Agouti is dominant gene; it's geotype is either AA (homozygous Agouti; carries two Agouti genes) or AS (heterozygous Agouti; meaning animal carries one Agouti gene and one Sapphire gene). You will need to spray down the cage with your choice of safe cleaning solution next. Golden Torts, with lighter patches of Yellowintermixed with the darker Golden. A Ruby Eyed hamster has red eyes and a diluted coat color. These hamsters come from arid regions of northern Syria and southern Turkey. Breeding and raising Syrian hamsters is an important responsibility. The reason for the variation is largely unknown, but carrying Black Eyed Cream will definitely turn the yellow black patches to cream. In the above cases, it also helps if the mate has no Cream or Umbrous genes. The breeder will be able to provide lots of information. For example, the allele rx codes for rex fur, but the allele Rx, (normal fur), may be found at the rex locus instead. A pure line is one in which the animals have no mutant genes except those inherent in their phenotype. Male Syrian hamsters are larger than females and tend to be more aggressive. The key to larger yields of Torts is the Yellow Black male (to the right and shaded in table). To reserve or hold a hamster, payment is required in full. Creamy Spotted hamster (descriptive label) Male honey banded. With just one copy, on cream based colours it will create a white flecking, while on others it will create a white belly. This can happen with the Greys, especially if the Grey is in combination (for instance, in the Grey Sables or Black Eyed Ivories). (Please note; these matings do not necessarily have to be incestuous; all that is necessary would be that the hamsters in the pairings had the appropriate genotype. Any gene that has its locus on the part of the X chromosome that is missing on the Y chromosome expresses itself differently in males and females. Place their cages in the same room as each other. The enclosure should have bedding, water, and a hide house. Scrap off any filth that has gathered on the sides of the habitat. You might see them squirming around in their nest. Simply put, if a parent has a recessive trait not found in the animal under question, that animal will carry the gene for the trait. Inside the hamster's cells are the chromosomes, which are tightly coiled lengths of DNA. Multiple genetically engineered Syrian hamster models for childhood obesity and dyslipidemia have been established, including CETP KO, HBB KO, SR-B1 KO, GLP-1R KO, and GLP-2R KO. These are dominant genes/ alleles and are given a code letter in uppercase. Take a clean paper towel and wipe down the enclosure until it is dry. Having happy and healthy pups is always the end goal. If a mother hamster is inexperienced or feels threatened, she may abandon or even cannibalise her pups. (This gene is rare now and renders males sterile by 10 weeks of age.) . In this study, we investigated whether the -SG gene is the primary cause for the cardiomyopathy of BIO14.6 hamsters using molecular and genetic analyses.. In addition, there is usually less risk of genetic weakness since the animals tend more to be The exception to this is the inclusion of a wild type gene pair if the animal's mate has a mutant allele in that pair. color, coat type and pattern you desire, at the same time avoiding matings that are likely to cause problems or just not further your goals. Punnett square. pp, A silvery coloured hamster with dark agouti markings. You do not need to provide the babies with anything currently. The disease is caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection and can affect several organ systems including the respiratory tract, urinary tract, neurological system, and cardiovascular system. Black-Eyed Cream This is one of the more popular hamster colors among Syrian hamster enthusiasts! The size of adult animals is around 6 in (15 cm) long, with a lifespan of two-Three years. 01-02-2013, 03:56 AM #3: souffle. Yellow. After a much closer look at the Cinnamon mother, we realized that she had a very faint grey cast to her crescents and belly. Before considering breeding Syrian hamsters, make an outline of a plan to execute. However, it is not always clear if a hamster has the Wh gene since it may be obscured by Dark Eared White or another pattern gene. Body mass is often within the range of 100-150 grams (3.5-5.3 oz), but Syrian hamsters from personal breeders will be within the range of 175-225 grams (6.2-7.9 oz). Baseline body weights were measured before infection. She was Umbrous. Suppose you have an Umbrous Golden that you think, from looking at its siblings, may carry Black Eyed Cream and Cinnamon. If the gene is dominant, it will show up, but if it is recessive, it wont show up, but the hamster will carry it, and if that hamster is paired up with another hamster who either has one or two copies of that gene, some of the offspring will show it. Since both animals are pure breeding, (homozygous), each has two copies of one allele at the Cinnamon locus. (In Roan, with the intermixing of colored and The hamsters gametes contain only one chromosome from each pair and therefore only one copy of each gene on that chromosome. If both parents carry a recessive gene in common, 1/4 of the offspring are likely to have the trait. Make sure your hamster has a lot of toys in its cage. Syrian hamsters (Mesocricetus auratus) are one of several rodents used in animal testing.Syrian hamsters are used to model human medical conditions including various cancers, metabolic diseases, non-cancer respiratory diseases, cardiovascular diseases, infectious diseases, and general health concerns. Privacy Policy. Each gene codes a different characteristic, e.g., eye colour. This will leave your natural odor on the bedding, which the newborns will smell. (Most mutations for defects are recessive so outcrossing decreases the chance that a defective trait will If this parent is homozygous, 100% of the offspring will have the trait in If your hamster is a little too jumpy to pick up safely, we recommend using a plastic cup to get you started. In Syrian hamsters, Dark Eared White masks all other colors coded for in the genotype. Rechnet alle genetischen Ergebnisse fr alle Mutationen und deren Kombinationen. All of the female babies will be tortoiseshell. Then, if she received both copies of the yellow gene, she can be a true yellow, with the cheek flashes and all. Even without consideration for show If the pedigree shows that there may be dominant colors masked, breed to any animal not having those colors (or the Dark Eared White gene). But over the years, a number of mutations appeared and now you can find a wide range of colours and coat types, some being common and other rare. Cat milk is the closest to hamster milk, and the animals will thrive if this needs to be given. Chop up broccoli into small pieces, or maybe give the pups a strip of a grated carrot. If left together, the hamsters will hurt each other, and possibly try to kill one another. The fur is extremely shiny but very thin and sparse. Certain genes inroduce various patterns onto the fur, beyond the anticipated Agouti or Self markings. bb, The hamster will be white with red eyes and dark ears. Available Hamsters - Hamster Tracks. The small pups will start to show signs of fur. Hamster Gene Calculators Hamster Gene Calculators Campbell Gene Calculator Winter White Gene Calculator Roborovski Gene Calculator Chinese Gene Calculator Back to Snowy Desert Gerbil Clan Special thanks to Katfor putting together the gene spreadsheets for these calculators. Pay attention to the critters wheel; the wheel will have bedding and feces stuck to the surface. A This will cause the momma hamster not to remember her pup. The litter contained all four colors plus Mink, Umbrous Golden and Sable. =). If the sperm was Y bearing, an XY male will be formed. Individual results will vary, but over many such matings the ratios will hold true). is the hamster, having no pigment, that is mistakenly referred to as an albino.). Also known as the golden hamster, the Syrian hamster is 5 to 7 inches long, and weighs between 4 and 8 ounces. Calculates all the possible genetic outcomes for any combination of breeding pair. (You can flip 4 heads in a row, just like you can get a litter of 4 yellow pups! As adults, Syrian hamsters are about the size of your hand. It consist of a reddish-brown coat, light grey underside, dark agouti markings and dark eyes. Just keep in mind, stastics dont yield precisely 50%, each pup just has a 50% chance of being yellow just like each time you flip a coin it has a 50% chance of being heads. Occasionally, pattern genes can produce completely pale ears, most common when the animal has more than one pattern. Do not leave any soap left. To the right is a photo of two young heterozygous form. The list is compiled from the shortest to the longest lifespan.

She will show this by standing very still. Mating one of these females to a Black male goes like this: The probability is that 1/8 of the litter will be Black Tort females (highlighted in table). For any trait that may be heterozygous, breed to an animal that is homozygous recessive. Spot cleaning will eliminate waste and help reduce the number of washings that will disturb the mother and babies. Muestra las probabilidades de cada cruce. Syrian hamsters also known as teddy bear or fancy hamster are great pets for new owners. These novel hamster models are being used by the Wang lab and other laboratories to study metabolic diseases. Hou rekening met recombinante frequenties voor: X-chromosoom loci (sl,cin,ino,op - 7%,3%,30%). Basic Genetic Information: Hamsters have 44 chromosomes Ovaries carry 21 autosomes and an X gamete Sperm carry 21 autosomes and an X or Y gamete Syrian hamster Karyotype courtesy of Knud Christensen, Ph.D., The Royal Veterinary Agricultural University, Denmark 10. Greene County Double Homicide, Articles S
