Question 1
Albinism is a recessive trait controlled by a single gene. If the frequency of albinos in a population is 0.25, what is the expected frequency of heterozygotes for this trait? (Hint: use the Hardy-Weinberg formula)
◦ 0.25
◦ 0.50
◦ 0.75
◦ 0.90

Question 2
Assume brown eyes is completely dominant to blue eyes and this trait is controlled by a single gene. If 400 people in a population of 10,000 have blue eyes, how many people would be expected to be heterozygous for this trait? (Hint: use the Hardy-Weinberg formula)
◦ 800
◦ 540
◦ 320
◦ 960
