For a given gene in a population, there are two alleles, A and a. The frequency of the dominant homozygote, AA, is 0.50; the frequency of the heterozygote, Aa, is 0.20; and the frequency of the recessive homozygote, aa, is 0.30. What is the frequency of the recessive a allele?

    Answer:0.548

    Explanation:

    In a population the genotype frequency = p2+2pq+q2=1

    gene frequency = p+q=1

    Where p is the homozygous allele (A)

    q is the recessive allele (a)

    Pq represent the heterozygote allele

    Given that p2=0.50

    2pq=0.20

    q2=0.30

    To get q=√0.30

    q=0.548

    The gene frequency for homozgous reccessive allele a is 0.548
