What do allele frequencies show when nonrandom mating occurs in a population?

A. Change and heterozygotes will be overrepresented in the population. B. Remain the same, but heterozygotes will be overrepresented in the population. C. Change and homozygotes will be overrepresented in the population. D. Remain the same, but homozygotes will be overrepresented in the population.
Alleles are basically the individual forms of a gene from your mother and father. You have two strands of DNA. One from your mother and the other from your father. Both have corresponding genes at corresponding lengths along the strands. However, each gene has two information sources, the mother strand and the father strand.
When a population is non-randomly mated, chances are that homozygotes will increase and these will be over represented in the population. This is because, homozygotes will tend to group together and have offspring with a similar gene sequence, with every generation having fewer and fewer heterozygotes.
