Question

You are studying a population of voles that show 100% positive assortative mating by phenotype. When you measure the genotype frequencies of the population you get the following data. Allele "A" is completely dominant to allele "a."PAA = 0.12PAa = 0.56Paa = 0.32What will the frequency of Aa be in the next generation?

A. 0.235B.0.189C.0.120D. 0.096E. 0.251

Answer 1

C. 0.120

Step-by-step explanation:

Assortative mating by phenotype means that individuals with similar phenotypes mate with one another more frequently than would be expected under a random mating pattern. Assortative mating can increase genetic relatedness within a population.

The answer is C. 0.120 because in assortative mating, the allele frequency does not change as it is non-random mating and mates are chosen based on their phenotypes.
