Question

What is the definition of genetic drift?

Answer 1

variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.

Answer 2

Explanation:

Genetic drift is a change in the frequency of an allele within a population over time. This change in the frequency of the allele or gene variation must occur randomly in order for genetic drift to occur. ... A population of rabbits can have brown fur and white fur with brown fur being the dominant allele.
