The gene pools of small populations are reduced primarily due to inbreeding. In small populations, individuals are more likely to mate with relatives, which can lead to a decrease in genetic variation and an increase in the expression of deleterious traits. This contrasts with larger populations, where there is more genetic diversity and a greater likelihood of mating between unrelated individuals.
