प्रश्न
“Migration may enhance or blurr the effects of selection”. Comment.
Advertisements
उत्तर
Migration may cause enrichment of the gene pool of such alleles that are being selected for, or nullify the effects of selection through replenishment of alleles that were selected against by nature.

Among the five factors that are known to affect Hardy-Weinberg equilibrium, three factors are gene flow, genetic drift and genetic recombination. What are the other two factors?
Gene flow occurs through generations. and 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.
