In a monohybrid cross of a brown male hamster (from a very longline of brown only hamsters) and a black female hamster (from avery long line of black only hamsters) all the offspring producedare brown.

a. What are the genotypes of the male and female parents?

b. What are the genotypes of the offspring?

c. If you mate 2 of the F1 offspring with each other, whatphenotypes of offspring will be expected in the F2 and in whatproportions would you expect them?

Part 2

Length of fur is also geneticall determined. The allele Lproduces long fur and its corresponding allele, l, produces shortfur. Long fur is dominant to short.

d. You mate 2 hamsters. Both are heterozygous for brown longfur. Would you expect any of the offspring to have black short fur?If yes, what proportion would have black short furt?

e. What proportion would have black long fur?
