Gene flow occurs through generations. Gene flow can occur across language barriers in humans. If we have a technique of measuring specific allele frequencies in different population of the world, can we not predict human migratory patterns in pre-history and history ? Do you agree or disagree ? Provide explanation to your answer.
Solution
Yes, I agree. Gene flow occurs through generations.
– By studying specific allele frequencies, human migratory patterns in prehistory and history can be predicted.
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 Genographics Project).
