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.

In the state of Hardy-Weinberg equilibrium, allele frequenciesMultiple choice question.are not changing.are undergoing natural selection.are evolving.are not stable.

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.

Select the five assumptions of the Hardy-Weinberg equilibrium that must be met to keep allele frequencies from changing.Multiple select question.No mutations occur.No natural selection occurs.Mating is random.Sexual selection takes place.Coevolution has occurred within the population.The population is large.There is no migration into or out of the population.

Hardy-Weinberg equilibrium is seldom seen in natural populations becauseMultiple choice question.selection takes place in natural systems.biologists cannot determine allele frequencies in wild animals.mating is usually random.wild populations are too large to use the mathematical calculations.

Hardy-Weinberg equilibrium will not occur in a population in whichMultiple Choicemutations do not occur.individuals mate at random.natural selection does not occur.individuals immigrate or emigrate.sexual selection does not occur.
