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

Four different mutant lines showing similar phenotype were identified from a genetic screen. When genetic crosses among these mutants were carried out, the first mutant was found to complement the second, third and fourth mutant lines. However, no other complementation groups do the four mutant lines belongs to?
