title: An allele-specific suppressor of white-coral in Drosophila melanogaster.
abstract: A new allele of white-coral (wco2) was isolated from Canton S after mutagenesis. Many common laboratory stocks were found to carry a suppressor gene (Su(wco2)) which alters the phenotype of wco2 flies toward wild-type. The Su(wco2) is allele-specific (it does not suppress wco), dominant, homozygous viable, located near Su(bwV1) on the right arm of chromosome 2, and shows a simple gene-dosage effect. The degree of suppression is sensitive to the genetic background. There appears to be selection for Su(wco2) in a genotype where it does not affect eye pigmentation.
