Genetic drift meaning simple
WebThe type (Genetic Drift) refers to an event in which the allele frequency of a population changes. The subtypes, Bottlenecking and Founder effect, are two different concepts. Imagine a colony of ants, half is red and half is black, if you step on the half dominated by red ants, then you have caused a bottleneck catastrophe which lead to the ...
