UV-induced mutagenesis at the CAN1 locus in the spores of the ady1 mutant (WSY1079 × WSY1086). (Top) Strains derived from the spores (side columns) of the ady1 mutant and from mating two spores (middle) of the ady1 mutant were exposed to UV light. The colonies growing up on the canavanine plate represented mutagenesis at the wild-type CAN1 locus in these strains. (Bottom, middle column) Diploid control (h1 × h2) that resulted from mating the two haploid controls (h1, WSY33; h2, WSY1086) were induced by UV for canavanine-resistant colonies.
