Developmental genetic analysis of lethal alleles at the ewg locus and their effects on muscle development in Drosophila melanogaster

Abstract The recessive X‐linked mutation erect wing (ewg), in Drosophila melanogaster, was characterized as a flightless behavioral mutant which specifically lacked the dorsal longitudinal flight muscles [1]. This mutation was mapped distal to the X chromosomal locus yellow, and further to the cytological segment 1 A 1 to 1 B2‐3 [2]. Several lethal complementation groups have been mapped to this i…
