Gene flow
From WikiLectures
In contrast to random changes in gene frequencies in small populations, which are the result of gene shift (a random change in gene frequency in small populations), a smooth change in gene frequency occurs in large populations due to gene flow. This occurs mainly between sub-populations through migrating individuals.
- A typical example is the steady decrease in frequency of the D alleles of the of the AB0 blood group system from approximately 0.6 in Western Europe to 0.3 in East Asia.
- Another example is the inflow of "white" genes into the gene pool of African Americans.
