Abstract

Summary: Results obtained from the germination of mature zygospores of support the hypothesis that normal meiotic processes operate in the sexual cycle of this fungus. The mating-type allele and a second allele, , segregated independently. When immature zygospores were germinated no such regularity was observed, but recombinant auxotrophic genotypes were recovered indicating a predormancy meiosis. However, prototrophic recombinants were not found. Bisexual heterokaryotic strains were also recovered from immature zygospore germinations but were auxotrophic. When cultures were obtained from outgrowths of both suspensors of a single zygospore the genotypes were not always those of the respective parents. This suggests the occurrence of nuclear movement from the immature zygospore to the suspensor cells.
