The Hardy-Weinberg equilibrium is used as a null hypothesis, i.e., if a population is in Hardy-Weinberg equilibrium, then ______.Multiple choice question.evolutionary change is not occurring in this populationall of the different alleles for a gene in a population have the same frequencyevolutionary change is occurring in this population

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.

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

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.

Which of the following would not be true for a population that is in Hardy-Weinberg equilibrium for a specific gene?Multiple choice question.No individuals are leaving or entering the population.Mating occurs randomly, regardless of the individuals' genotypes.Natural selection favors individuals with a heterozygous genotype.No new mutations are occurring in the sequence of the gene.

Select all of the following that occur in natural populations and that violate the assumptions of the Hardy-Weinberg equilibrium.Multiple select question.migration among populations occursno mutation occursmating is often nonrandomallele frequencies can change due to chance eventsallele frequencies are not changed by natural selection
