Construct: Deletion of homology region A, bases 2897-2986 (numbering according to FBrf0048095).
su(Hw)ΔA/mod(mdg4)ul is an enhancer of phenotype of y2
mod(mdg4)ul, su(Hw)ΔA, y2 has macrochaeta phenotype
mod(mdg4)ul, su(Hw)ΔA, y2 has unguis phenotype
mod(mdg4)ul, su(Hw)ΔA, y2 has wing phenotype
mod(mdg4)ul, su(Hw)ΔA, y2 has abdomen phenotype
Fails to suppress the y2 mutant phenotype when crossed into a su(Hw)V background. When crossed into a mod(mdg4)ul mutant background, su(Hw)ΔA causes a slight enhancement of the y2 phenotype in the bristles and tarsal claws, while the pigmentation of the wing and abdomen darkens somewhat.
