In a population of 1,229 lemon sharks that is in Hardy-Weinberg Equilibrium, 901 have yellow eyes while the remainder have brown eyes. The brown eye trait is recessive to yellow eyes. How many individuals would you expect to be homozygous for yellow eye color?

Imagine a species of desert rat that has either a brown coat (homozygous BB), a white coat (homozygous WW), or a mottled coat (heterozygous BW). What are the genotype frequencies in a population of 745 rats, 263 of which have brown coats (assuming they are in Hardy-Weinberg equilibrium)?

What are the allele frequencies in the gene pool of gametes produced by these rats?

Now assume that these rats carry worms that can spread human disease, and the ones with white in their coats are more easily caught in traps put out for them. If you start again with that same population of 745 rats and people trap 197 white ones and 61 mottled ones, what are the genotype frequencies after the threat has passed and people stop trapping rats?

What are the allele frequencies in the gene pool of gametes produced by the survivors?
