Genetic complementation analysis of Drosophila eye color mutants

Genetic complementation testing among nine distinct Drosophila eye color mutants reveals five complementation groups corresponding to five genes. Five mutant alleles of white mutually fail to complement and are assigned to the same gene. The other four mutants each complement one another and the white gene mutants and are assigned to their own gene. Complementation is indicated by “+” and no complementation by Genetic complementation testing among nine distinct Drosophila eye color mutants reveals five complementation groups corresponding to five genes.
