Question

What is the meaning of genetic drift?

Answer 1

a) Genetic drift - along with natural selection, mutation, and migration - is one of the basic mechanisms of evolution.
b) Genetic drift is the change in the frequency of a gene variant (allele) in a population due to a random sampling of organisms.
c) The alleles in the offspring are a sample of those in the parents, and chance has a role in determining whether a given individual survives and reproduces.
