Once they walk away from each other, remove the hamsters and put them back in their separate cages. Provide the Syrian hamsters with a comfortable environment. Mutations are changes in the genetic code. It's important to keep in mind though that even when the genes aren't mentioned, they do still exist in the hamster's chromosomes. )Finally, and this is the most complicated part a female yellow is always tort, UNLESS it was bred from a yellow dam (mom) and a yellow sire (dad).

A planned breeding program to develop a recessive trait starts with an animal that has that trait. these hamsters results in litters with a variety of phenotypes which is pleasing to many people. If a pure breeding Cinnamon male is mated to pure breeding Golden female, the resulting pups are all golden. When these gametes join together the following crosses can occur. Dominant Spot distributes white over the entire upper surface, matching the distribution of the other two colors. 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. They are part of the rodent family which takes up 40% of the mammalian orders. The Syrian can live up to 3 years in captivity, and some have been known to live past that. The same will be true of the eggs that his sister makes. 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.

Sometimes, the presence of Lg or Ds in the parents is not obvious. 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. Potential yields of the desired types are halved when a pattern gene is considered since 1/2 the offspring will be unpatterned.

This is acheived by a normal cell division, followed immediately by each cell dividing in two again. A Tricolor is a Tortoiseshell with a white pattern gene. For this reason, the allele at each locus that is not a mutation is known as wild type. Phenotyping your hamster provides genotype information about recessive genes only if they are present in pairs; it does not tell you if the animal is carrying recessives. Let them be for about a week.
