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
