Summary
Meiosis in diploids of Saccharomyces cerevisiae either homozygous or heterozygous for the dmt gene result, in about 5% of the meiotic products, in spores which have undergone an interconversion at the mating-type locus. Some of these interconversions appear to result in the generation of spontaneous omni-mating strains. This phenomenon has now been quantitated and the distribution of mating-type loci in these “natural”, omni-mating types determined.
