प्रश्न
Very short answer question.
State the Hardy – Weinberg equilibrium.
Advertisements
उत्तर
- The Hardy-Weinberg equilibrium law states that at the equilibrium point, both the gene (allele) frequency and genotypic frequency remain constant from generation to generation.
- generation, in the diploid, sexually reproducing, large, free interbreeding population in which mating is random, and there is the absence of any other factors that change the allele frequency

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?
