Paisley · Answer 1

c) Genetic drift

Explanation:

Change in the relative frequency of different genotypes (genetic appearance of an individual) in a small population, Leading to the chance disappearance of particular genes as (gene deletion) individuals die or do not reproduce. Genetic drift is the change in the frequency of an existing gene variant in a population due to random sampling of organisms. The alleles in the offspring are a sample of those in the parents, Changes has a role in determining whether a given individual survives and reproduces. Genetic drift means that the gene is totally deleted from certain population due to death or in capability of reproduction of an individual. Genetic drift occur when their is change in allele frequency occur randomly it leads to genetic drift.
