1. Let's say that in seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes for long whiskers & the recessive allele (w) codes for short whiskers. What percentage of offspring would be expected to have short whiskers from the cross of two long-whiskered seals, one that is homozygous dominant and one that is heterozygous? Explain your answer and use a punnett square.
2. You are experimenting with flies in which red eyes (R) are dominant over white eyes (r). If the mother has white eyes, and the father is heterozygous. What are the expected results for genotype and phenotype?

1. Parents are WW x Ww.
Offspring are 1 WW : 1 Ww ... all long-whiskered.
2. Mother is rr. Father is Rr.
Offspring are 1 rR : 1 rr ... 1 red: 1 white.
