In the first row of the table above, we record the initial genotypic frequencies before selection has acted. If mating has been random (an assumption of the model), the genotypes will have the Hardy–Weinberg equilibrium frequencies of p2, 2pq, and q2) In the second row of the table above, fitness values of the corresponding genotypes. In the third row the proportion of the population represented by each genotype after selection is obtained by multiplying the initial genotypic frequency times its fitness. The frequency of A allele after selection will be

Parents that are homozygous for different mutations a, b and c are crossed, producing offspring that are heterozygous as following

aa X bb        =  ab  (X)          

 bb X cc         =  bc  (Y)

aa X cc          =   ac  (Z)

If a and b belong to same locus but b and c belong to different locus then phenotype of heterozygote
