How does nonrandom mating affect the gene pool?

The effect of nonrandom mating is that biologically successful individuals' genes dominate the gene pool

Per quiz answer the dominant genes in a population become more abundant

Explanation:

see above

In non-random mating, organisms may prefer to mate with others of the same genotype or of different genotypes. Non-random mating won't make allele frequencies in the population change by itself, though it can alter genotype frequencies.

Explanation:

Renewable sources of energies are those who can grow again, such as trees and plants, or that can always reappear, such as wind and solar energy. Nonrenewable energy, however, cannot be regenerated, like oil and coal, or are mined minerals.

The answer here would be A, as a gold necklace is made of a mined substance, which is nonrenewable.
