Final answer:
Heterozygote inferiority reduces genetic diversity within populations by pushing alleles to fixation. Inbreeding depression decreases reproduction and survival, resulting in low genetic diversity. Populations with low genetic diversity have lower evolutionary capacity.
Step-by-step explanation:
Heterozygote inferiority reduces genetic diversity within populations by pushing alleles to fixation. Inbreeding, which is the mating of closely related individuals, can lead to inbreeding depression, a decrease in reproduction and survival. Inbreeding depression reduces genetic diversity within a population by increasing the frequency of rare alleles. Populations with low genetic diversity have a narrower genetic template and lower evolutionary capacity to adapt to changing environments.
