Question

multiple choice question
genetic variation in a population results from evolutionary forces that cause changes in

o migration rates
o allele frequencies
o predatory habits
o population size

Explanation:

Genetic variation in a population is due to changes in the frequencies of alleles (different forms of a gene) caused by evolutionary forces like mutation, natural selection, genetic drift, and gene - flow. Migration rates, predatory habits, and population size can influence allele frequencies indirectly but the direct factor related to genetic variation is allele frequencies.

Answer:

allele frequencies
