Define Genetic drift. Mention the types.

Text Solution

Verified by Experts

Yes, I agree. Gene flow occurs through generations. By studying specie allele frequencies, we can predict the human migratory patterns in prehistory and history. Studies have used specific genes/chromosomes/ mitochondrial DNA to trace the evolutionary history and migratory patterns of humans the project is known as the Human Genographic Project
