WebExamples of Genetic Drift. To exemplify the genetic drift, let’s take a hypothetical example of a population of 100 rabbits that live in the woods. All the rabbits in the woods have various colours of their coats. The colours are black, grey, white, tan, brown and red. In the population of the rabbits, the alleles creating the coat colour are ... WebTo get a feel for genetic drift, consider a population at Hardy-Weinberg equilibrium for a gene with two alleles, A and a. Let p = the relative frequency of the A allele, let q = the relative ...
