Abstract

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
