1-A population of 4,000 butterflies at Hardy- Weinberg equilibrium contains 360 indviduals with bentantennae- a recessive phenotype ( genotype aa). What is the frequency of the recessive allele

(a) in the population after 6generation?

2-A marine biologist captures 5,000 shrimp in a largeseine net. Surprisingly, 4,500 show mottled coloration- therecessive phenotype ( genotype cc) , while only 150 show tancoloration – dominant phenotype ( genotype Cc or CC)

a) Is the population of the shrimp at geneticequilibrium?

b) Would you expect the sample aboveto be representative of the wild population of shrimp at large?

3-Suppose that 75% of the humans on prince Edward Island havelong eyelashes ( genotype Ee or EE)

A) What is the frequency of the dominant allele, E?

B) What percent of the islanders would beheterozygous for eyelash lenth?
