In Human Populations,inbreeding Results In

Question

In human populations,inbreeding results in
A) fewer heterozygotes and more homozygotes.
B) more heterozygotes and fewer homozygotes.
C) about equal numbers of homozygotes and heterozygotes.
D) only heterozygotes.
E) Hardy-Weinberg equilibrium.

Accepted Answer

Inbreeding increases the frequency of homozygotes and decreases the frequency of heterozygotes. This is because offspring of closely related individuals have a higher probability of inheriting the same alleles from both parents, resulting in more homozygosity.
