Question

1. In a population of people off the coast of New Quinoa, a recessive allele for albinism is quite frequent. One in 100 people of the population are albino and homozygous recessive for this allele. Assuming Hardy-Weinberg conditions, what is the frequency of people that are homozygous dominant for the condition?

a. 1%

b. 18%

c. 81%

d. 99%

2. In a population of dragonflies, abdomen color varies between dark red and light yellow. The alleles for these colors show incomplete dominance with heterozygotes being intermediate in color. Dragonflies with intermediate coloration are more likely to be eaten by birds, and so the population tends to have higher frequencies of dragonflies that are homozygous for abdomen color. This is consistent with:

a. Female mate-selection

b. Heterozygote advantage

c. Genetic drift

d. Disruptive selection
