    If the population is in Hardy-Weinberg equilibrium (the genetic variation in a population will remain constant through the generation in the absence of disturbing factors) then p2+2pq+q2=1 or p+q=1

    p is the frequency of allele (dominant)

    q is the frequency of allele (recessive)

    p2 is the frequency of dominant homozygous genotype

    2pq is the frequency of heterozygous

    q2 is the frequency of recessive homozygous genotype If p=0.4 then q=0.6
