[Questions 14 -16] Consider a population of mice that feeds on grass. An enzyme the mice need to digest the grass is encoded by a single gene with two alleles in the population, C and c. Individuals that are homozygous CC have an easier time breaking down the fibrous material in grasses. Initial allele frequencies in the population are equal, and the population is in HW equilibrium. A drought then kills all grasses except those that are fibrous and more difficult to digest. During the drought, homozygous cc individuals and heterozygous individuals have equal fitness, while homozygous CC individuals have higher fitness than the other two genotypes.
This is an example of stabilizing selection. O a. True O b. False Clear my choice The drought should increase the frequency of heterozygotes in the population. a. True O b. False Clear my choice
