[Localization of E(wa) in Drosophila melanogaster using rearrangement].

Abstract excerpt

The white-apricot (wa) allele differs from the wild type white gene by the presence of the retrovirus-like transposable element copia within the transcription unit. The activity of wa is reduced in trans by a semidominant mutation in the gene Enhancer-of white-apricot (E(wa)). The map position of E(wa) is refined by analyzing recombination among three genes: px, E(wa) and sp. The recombinational distance between...
