Why are genetic studies being carried out on African populations?
All humans trace their heritage to Africa, where humans first evolved and then migrated around the globe. Previous studies, such as the International HapMap Project, show that African populations have the greatest amount of genetic variability. Genetic variation between individuals has been shown to affect the risk of developing different diseases. By studying Africans populations with the greatest amount of genetic variation, especially in relation to clinical findings and environmental information, researchers expect to learn a great deal about the genetic roots of diseases that afflict Africans and other human populations across the globe.
- do genetic studies of contemporary populations reliably represent prehistoric populations of Pacific Rattus exulans?
- What is the importance of heterozygotes, the heterozygote advantage, in maintaining genetic variation in populations?
- Why bother with the Hardy Weinberg Formula when most populations in nature don meet genetic equilibrium?
