What (if any) change in genotype frequencies is most likely to be seen in the next generation of a population that was initially at Hardy-Weinberg equilibrium but where individuals start mating randomly according to phenotype? Question 15 options: A decrease in population size An increase in population size An increase in the frequency of homozygotic individuals No change in genotype frequencies A decrease in the frequency of homozygotic individuals A decrease in the frequency of heterozygotic individuals

Step 1
Step 1: Initially, the population was at Hardy-Weinberg equilibrium, which means that genotype frequencies remain constant from generation to generation when certain conditions are met (random mating, no selection, no mutation, no migration, and large population Show more…

14) Whenever diploid populations are in Hardy-Weinberg equilibrium at a particular locus A) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. B) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. C) this means that, at this locus, two alleles are present in equal proportions. D) the population itself is not evolving, but individuals within the population may be evolving.

If there is a mutation occurring in a population that turns allele "A" into allele "a" (and no other mechanisms of evolution are at work in the population), which of the following will be true? Allele frequencies will stay the same over time The frequency of "A" will increase over time The frequency of "a" will increase over time We can't tell what will happen to the allele frequencies in the population, given this information.

If within a large population no mutations occur, no migration occurs, all mating is random, and each individual has an equal chance of reproducing, which of the following will probably happen? - Allele frequencies will change to favor the dominant allele. - Allele frequencies will change to favor the recessive allele. - Allele frequencies will not change. - A bottleneck will occur in the population. - The population will become extinct.
