A mutator factor in a strain of Drosophila melanogaster: identified by use of mutation, reversion rates and male recombination.

Abstract excerpt

A set of 1,000 "mutation accumulation" lines Drosophila melanogaster, which originated from two different wild-type, lethal-bearing second chromosomes (Yamaguchi and Mukai 1974; Mukai and Cockerham 1977), was examined for evidence of a mutator factor by using the occurrence of recessive visible mutations and male recombination to identify its presence. The 1,000 lines were screened at approximately generation 240...
