Final answer:
A large number of different alleles in a population leads to a greater variety in the gene pool, resulting in higher genetic diversity. variety, gene pool, population, and genetic diversity. Population genetics deals with the study and implications of genetic variance within populations. The option (A) is correct.
Step-by-step explanation:
A large number of different alleles means a large variety of different gene pools in the population, and therefore a high genetic diversity.
Population genetics is the study of how selective forces change a population's genetic structure through changes in allele and genotypic frequencies. For example, in humans, multiple alleles determine blood types, such as in the ABO blood system, which can result in a diversity of possible genotypes within the population. This genetic variance increases when there is a greater diversity of alleles and genotypes in the population.
Increased genetic variance is beneficial for a species' survival as it can reduce the risks associated with inbreeding. This is important in conservation efforts, where scientists try to maintain or increase genetic variance to preserve as much phenotypic diversity in the population and thus prevent the negative effects of having a limited gene pool, such as inbreeding depression. Therefore, option (A) is correct.
