A change in allele frequencies that occurs by chance and that tends to eliminate alleles in a population rather than increase diversity is calledMultiple choice question.genetic drift.selection.migration.nonrandom mating.

Genetic drift is a change in allele frequencies that occurs by ______ and, unlike mutations, it tends to eliminate alleles from the population.Multiple choice question.chancedirectional selectionnatural selectionrandom mating

When allele and genotype frequencies are not changing between generations, the population is said to beMultiple choice question.selected against.undergoing directional selection.in Hardy-Weinberg equilibrium.reproductively fit.

How does natural selection act to change allele frequencies?Multiple choice question.favors phenotypes that increase reproductive successeliminates alleles by random chancecreates new allelesmoves new alleles into a population
