Genotype frequencies may be altered by

B) the founder effect.
C) gene flow.
D) nonrandom mating.
E) All of the above

Question

Quizplus · Accepted Answer

All of the listed factors (genetic drift, founder effect, gene flow, and nonrandom mating) can alter genotype frequencies within a population. Genetic drift and the founder effect both involve random changes in allele frequencies within a small population, while gene flow involves the transfer of alleles between populations. Nonrandom mating can lead to changes in genotype frequencies by altering the likelihood of certain genotypes mating with each other.
