The female is homozygous dominant for hair color and heterozygous for eye color. What then would be her genotype?

The male is heterozygous for both traits, which means his genotype is WwBb. You were also informed that each homologous chromosome contained one dominant and one recessive allele from each of the two traits. So, which of the following images represents the chromosomes of the male mouse?

Now, given the above chromosomes, what gametes will the male mouse produce?

You should now have all the information needed to perform a punnett square and determine the types of offspring produced:

Your punnett square should look similar to the one below. If it does not, review the material on gamete formation and how to set up the punnett square and try again.

Now count up how many offspring of each genotype and phenotype you have.
