Characterization of a hypermutable strain of Drosophila simulans

A hypermutable strain of Drosophila simulans that originated from a single spontaneous mutant male was characterized. Seven different mutations were isolated from roughly 100 generations of offspring. The genetic analysis of the viable mutants showed two mutations on the X chromosome, one in the lozenge locus and the other in the ruby gene. The autosomic mutations characterized were a dpp-heldout-like, a blistered-like and a homoeotic dominant mutant with an antenna-to-leg transformation and ectopic eyes that we called Zoinho-napata.
