Population frequency

  1. May 7, 2007 #1
    A population has two alleles, B and b. the allele frequency of B is 0.73. what is the heterozygotes frequency, if the population is in H-W equilibrium?

    two major important equations for Hardy-Weinberg:
    p + q = 1
    and p^2 + 2pq + q^2 = 1

    You know 'p' in your problem: it is .73 Therefore you must know that 'q' is .27
    since you know p = .73 and q = .27 you can find 2pq (which is the heterozygote frequency)
