This is the end of the genetics tutorial. When you purchase Syrian hamsters from a pet store, you have no idea how old they are, or what their parents look like. Their different colors will also begin to appear. Like all animals, the genes that a hamster inherits from its parents, (the genotype), affect the way it looks. You can choose between a plastic cage that has a wire on the top and a glass aquarium. This is acheived by a normal cell division, followed immediately by each cell dividing in two again.

The smallest cage you can put your Syrian hamster into can be 1x2x1 feet. rdrd, If the hamster has two copies of this gene they will be completely white, with deformed eyes, poor teeth, and will also be deaf. Chromosomes within a pair have the same slots for genes coding for particular characteristics in the same order. Most Self-colored hamsters have a single color in the coat hair that extends from the base to the tips. A dihybrid cross results in a 1:2:1 genotype ratio. standards, outcrossing is a good way to maintain the production of vigorous animals. Give tiny portions of light vegetables.

(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. Mother hamsters that are older than 8 months for their first litter may have other kinds of pregnancy problems. The options for a gene for one particular slot, (locus), are called alleles. Males get their singular yellow gene from their mom. Changes in her temperament will start to occur. If both parents carry a recessive gene in common, 1/4 of the offspring are likely to have the trait. For every gene pair that is heterozygous, the recessive trait is highly likely to appear in the litter, either alone or in combination. Self Colored Syrian Hamsters "Self" means the hamster is, genetically, all one color. Syrian hamsters have 22 pairs of chromosomes and some of the genes within those chromosomes determine what the hamster will look like.

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.
