Abstract:
5 white-locus mutants of Drosophila melanogaster, representing 5 different sub-sites, were treated with EMS and tested for reversion to wild-type. 4 of them were genuine mutants and one was not. Moreover, the ability of the 4 mutants to revert to wild-type differed from one another which therefore reflects a qualitatively distinct alteration in the genetic material delimited by each mutant.
