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

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.

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.

If we find evidence that a population is experiencing changes in allele frequencies from one generation to the next, we say that this population is which of the following?Multiple choice question.Not in Hardy-Weinberg equilibriumNot evolvingIncreasing in sizeIn Hardy-Weinberg equilibrium

What conclusion can be drawn from the observation that a population is not in Hardy-Weinberg equilibrium?Multiple choice question.Allele frequencies are stable from one generation to the next.Evolutionary forces are affecting the population.Genotype frequencies but not phenotype frequencies are the same from one generation to the next.The population is isolated from other populations of the same species.
