WebGenetic distance is a measure of the genetic divergence between species or between populations within a species, whether the distance measures time from common ancestor or degree of differentiation. [2] Populations with many similar alleles have small genetic distances. This indicates that they are closely related and have a recent common ancestor. WebAug 14, 2012 · Population genetic studies provide insights into the evolutionary processes that influence the distribution of sequence variants within and among wild populations.
