WebMar 17, 2024 · Definition: Genetic drift is defined as the changing of the number of available alleles in a population by chance events. Also called allelic drift, this phenomenon is usually due to a very small gene pool or … WebGenetic drift can also contribute to the evolution of new species by producing genetic divergence across populations. The transfer of individuals or the genes that they carry from one group to another is an example of a mechanism of evolution known as gene flow. WebGenetic drift can cause big losses of genetic variation for small populations.

WebDec 8, 2024 · Genetic variation is strongly influenced by the multi-generational shifting balance among new alleles arriving through mutation and immigration and the loss of alleles to genetic drift (Row et al., 2016; Wright, 1931 ).
