Question

What is the correct answer and why are the rest wrong? D) 4-+2-3-1 9) Whenever diplold populations are in Hardy-Weinberg equilibium at a particular locus this means that, at this locus, two alleles are present in equal proportions. (23.2) B) natural selection, gene flow, and genetic drift are acting equally to change allele frequency C) the population is not evolving, but individuals within the population may be evolving thea llele and genotype frequencies should not significantly change from one generation to the next

Explanation / Answer

Answer: None of the options are correct.

Explanation:
For a population to be in HW equilibrium for a given locus, both the alleles do not have to be in equal proportion. The population should not be under natural selection or genetic drift. There should not be any gene flow due to migration. There is no evolution (either at the population or at the individual level) in HW equilibrium.

In HW equilibrium, allele frequencies do not change from one generation to the other. But genotypic frequencies may change. The proportion of alleles in homozygous and heterozygous conditions may change.
