F. Claire Hankenson, Gerald L. Van Hoosier Jr., in Laboratory Animal Medicine (Second Edition), 2002. B. Genetics. Golden hamsters have a diploid chromosome number of 44. Numerous mutations have been introduced since the establishment of the Syrian hamster as a laboratory animal in the 1930s (Yoon and Peterson, 1979).Eighteen of the mutations involve coat and eye color; the earliest mutations. There are a couple of situations in which you cannot tell a Mottled or an Anopthalmic hamster. We’ll discuss each separately since the dwarf genes and gene combinations are a bit different than the Syrian ones. Masking the Mottled Gene Some colors “hide” or “mask” other colors or patterns. Let’s take a common example.
Sex-linked yellow in hamsters—phenotype and genetics:. Commercial suppliers of Syrian hamsters to research laboratories carry few, if any, coat color variants. We identified a major pet store supplier in the California central valley, imported several different coat color variants, and established standardized pedigrees from seven tortoiseshell females and six black males to confirm and.

Syrian Hamster Colours Derived From Combining Mutations. By combining different colour mutations more colours can be created. These colours do not occur in the first generation mating but occur when the offspring are mated together. Click on any colour name to view a fuller description and more pictures.
While hamster colors may seem like a surface issue, there is in fact a large body of science behind how genetics influences hamster coat colors. Hamster coat color genetics are of course akin to genetic science in the broadest sense, as fur and eye color are determined by genes inherited from each parent. Syrian Hamster Colors and Coats. The Syrian hamster is commonly called Golden Hamster, referring to the wild colour. 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. Some have been standardized by clubs for show purposes. Genetics and Inheritance Introduction Genes in the Syrian Hamster Simple Inheritance Complex Inheritance Sex Linkage Introduction. Like all animals, the genes that a hamster inherits from its parents, (the genotype), affect the way it looks.The animal receives genetic information from its parents in their eggs or sperm and, in the same way, passes the information on to its own offspring.
Colours of the Syrian hamster can be described in three ways: as "self", "agouti" or "combinations". Self colours are a consistent coat colour with the same colour topcoat and undercoat. Agouti hamsters have a different, lighter undercoat and markings around the eyes. As always, you should make sure that when you a breeding you follow a breeder’s code. Learn and read about genetics, not only the genetics of your hamster, but genetics in general. Know what to look for when you’re breeding. You shouldn’t just breed for “pretty colours” but instead breed to improve the species overall. In the course of analysis of ENU-induced mutations in Syrian hamsters, a novel dominant anophthalmic white mutant ( WhV203 ) with hearing loss was recovered. Because of this phenotype and a close linkage to the Tpi gene, the Mitf gene was considered as a candidate gene. In the Mitf cDNA, a deletion of 76 bp covering the entire exon 7 was detected. Further molecular analysis revealed a T → A.
Syrian hamster – colours and patterns Thanks to advance breeding techniques and practices, Syrian hamsters now come in a variety of coat types, patterns and colours! Coat Types: Short haired, long haired, rex coated, satin coated. Patterns: Banded, Dominant spot, Tortoiseshell (bi-colour), Calico (tri-colour), roan. Colours: Normal (golden), cream, cinnamon, sable, yellow, yellow black. For example, Hamster A is a blue female and Hamster B is a blue fawn male. Bred together, they produced 8 pups. 4 opals, 2 blues, and 2 blue fawns. If Hamster A is a pure blue female (aa dd), and Hamster B is a pure blue fawn male (dd pp), they are supposed to produce 8 opals [dd], 2 of which will have unpaired black genes [a_] and two will. Hamsters are rodents (order Rodentia) belonging to the subfamily Cricetinae, which contains 19 species classified in seven genera. They have become established as popular small house pets. The best-known species of hamster is the golden or Syrian hamster (Mesocricetus auratus), which is the type most commonly kept as pets.Other hamster species commonly kept as pets are the three species of.
Basics of Genetics in Syrian Hamsters . Inside the nucleus of each cell of a hamster is something called Deoxyribonucleic Acid or for short DNA. DNA is a molecule that contains a blueprint of instructions. Genes are made of DNA. Every detail about the hamster is recorded in the genes including its appearance and temperament. The Syrian hamster is also most commonly know as the golden hamster as this is the original 'wild' colour. However, over the years many different colours, coat lengths, patterns and coat types have now developed due to mutations. Here I have listed a wide variety of the colours/coats that are around today although it is not possible to list. Syrian Hamster Colour Combinations. November 17, 2017 | No Comments. SYRIAN GENETIC COLOUR COMBINATIONS. GOLDEN : AGOUTI: BLACK: MUTATION: CINNAMON: MUTATION: CREAM (BLACK-EYED) MUTATION: GREY (DARK) MUTATION: GREY (SILVER). ← Syrian Hamster Genetics and Inheritance. Breeding Syrian Hamsters.
Syrian hamsters can come in many different colors including, gray, black, yellow, red or a mixture of several different colors. Beige – Produced by breeding a two hamsters with the rust and dark gray genes, the beige color variety is often the smallest and less robust of the litter . Genetics of Sex-linked yellow in the Syrian Hamster Article (PDF Available) in Genetics 181(4):1427-36 · March 2009 with 125,341 Reads How we measure 'reads' The Syrian hamster has the greatest variety in colours, basically because it has been bred for much longer than the other species, and therefore there has been more time for mutations to occur. Syrian Colours, Coats and Patterns. Syrian Coat Types. Hair Length: Syrian hamsters can have either short hair or long hair. The long hair gene is.
Roan Syrian Hamster. One mutation, the Anophthalmic White mutation can produce two different types of white pattern – White Bellied and Roan.. For showing the hamster is required to have a marbled appearance of colour over the back. With non-cream based colours (such as Golden, Cinnamon, Yellow, Dark Grey, Black, Silver Grey, etc) the.
