Summary
Two new parameters of the third chromosome mutator gene, mu, in Drosophila melanogaster are described. The mutator significantly alters both meiotic chromosome disjunction and crossing over in females, but not in males. In meiotic phenotype, the mutator resembles several recently described “meiotic” mutants of D. melanogaster. However, previous studies have demonstrated that the mutator also functions premeiotically. The mutator appears to be a unique mutant which functions exclusively in females during both mitotic and meiotic cell divisions.
