Displaced genital arch in a Drosophila melanogaster male
Drosophila melanogaster mutant ebony (e) is characterized by its pigmentation defects in the adult cuticle (Bridges and Morgan, 1923); eyegone (eyg) has been described as having head and eyes much smaller than normal (Ives, 1942); and the vestigial (vg) locus seems to be only involved in wing develo...

| Sumario: | Drosophila melanogaster mutant ebony (e) is characterized by its pigmentation defects in the adult cuticle (Bridges and Morgan, 1923); eyegone (eyg) has been described as having head and eyes much smaller than normal (Ives, 1942); and the vestigial (vg) locus seems to be only involved in wing development (Bridges and Morgan, 1919). While analyzing the F1 offspring from the parental cross between the D. melanogaster strains e eyg and vg, a particular fly was observed. It was a male, with no extended wings and normal color (although slightly darker because it was heterozygote for e). Interestingly, its genital arch was displaced from its normal position. It was not located in the ventral tip of the abdomen, instead it was displaced almost 90 degrees towards the end of the abdomen (Figures 1 and 2). The abdominal area where the genital arch should be was covered with a thin tegument (Figures 3 and 4). Sex combs were properly located. The animal died by accident nine days after emerging and left no progeny (he was caught in the culture medium) [...]. |
