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
