Nonrandom mating tends to the frequencies of genotypes.

a. increase; homozygous

b. decrease; homozygous

c. increase; heterozygous

d. decrease; homozygous recessive

e. increase; homozygous dominant

Answer;

A. increase ; homozygous

Explanation;

-Nonrandom mating occurs when the probability that two individuals in a population will mate is not the same for all possible pairs of individuals. When the probability is the same, then individuals are just as likely to mate with distant relatives as with close relatives -- this is random mating.

-Nonrandom mating tends to increase the frequencies of homozygous genotypes. Nonrandom mating can take two forms namely; inbreeding and outbreeding.

-Inbreeding changes genotype frequencies, not allele frequencies: Homozygotes increase in frequency, heterozygotes decrease in frequency.
