Mutations in four nuclear genes, kar1 cdc4, 28, and 37, block or impair nuclear fusion during conjugation of Saccharomyces cerevisiae. Mutations in all four genes are recessive for the caryogamy defect; in matings between diploid cells both of which are heterozygous for any one of the four mutations (-/+ X -/+), caryogamy occurs with normal proficiency. However, mutations in all four genes are "nuclear dominant"; that is, both parent nuclei must contribute one wild-type allele of each gene for… CONTINUE READING
