The frequency of alleles in a population that is in hardy-weinberg equilibrium
a)changes in each successive generation.
b)is less important than the frequency of genotypes.
c)shows evidence of the process of natural selection.
d)remains the same over several generations.

The correct answer is option D

According to the Hardy-Weinberg Equilibrium the overall frequency of alleles remains same in a population. This law states that the alleles population remains same in the over all generation in the absence of the evolutionary evidences.

These evidences may include genetic drift, assortative mating, natural selection, genetic hitchhiking, population bottleneck.

d. groundwater flows through the subsoil and deposits minerals.

the correct answer is 2 and 4
