Imagine you are a geneticist interested in studying a newly discovered species of very colorful birds. You have found that a sin
kolbaska11 [484]

The frequency <em>p</em> of the yellow (A) allele is  <em>p</em>= 0.3

The frequency <em>q</em> of the blue (a) allele is  <em>q= </em><em>0.7</em>

Hardy–Weinberg equilibrium,  states that allele and genotype frequencies in a population will remain constant from generation to generation. Equilibrium is reached in the absence of selection, mutation, genetic drift and other forces and allele frequencies p and q are constant between generations. In the simplest case of a single locus with two alleles denoted A and a with frequencies f(A) = p and f(a) = q, the expected genotype frequencies under random mating are f(AA) = p² for the AA homozygotes, f(aa) = q² for the aa homozygotes, and f(Aa) = 2pq for the heterozygotes.  

p²+2*p*q+q²= 1       p+q= 1     q= 1-p

yellow (p²)= 9%= 0.09               p= √0.09= 0.3

green (2*p*q)= 42%= 0.42        

blue (q²)=49%= 0.49                q=1-0.3= 0.7 <em>or</em> q= √0.49= 0.7
