    In a random mating population of 40,000 individuals, percentage of homozygous dominant individuals is 49% then find out the percentage of homozygous individuals?

    Solutions

    Homozygous individuals = p2 + q2
    p2 = 0.49
    p = 0.7        p2 + q2 = (0.7)2 + (0.3)2
    q = 1 – P = 1–0.7   = 0.49 + 0.09
