Lactose digestion capacity in Tokelauans: a case for the role of gene flow and genetic drift in establishing the lactose absorption allele in a Polynesian population.

Abstract excerpt

Throughout the Pacific, lactose absorption occurs at rates of 0-46%. Most authors explain the current rate of lactose absorption in the Pacific in terms of gene flow with Europeans. However, researchers have not been able to determine the exact historical circumstances of the introduction of the lactose absorption gene. The availability of genealogical material, historical information, and mal/absorption...
