Human Population Genetics: Drift and Migration


Genetic drift is the effect of changes in genetic composition of a finite population, due to random replacement of alleles from one generation to the next. Migration effect specifies alterations caused by exchange of genes between populations.

Keywords: random genetic drift; gene flow; fixation index; effective population size; gene diversity; founder effect; human genome diversity
