Defective karyogamy in meiotic segregants of a Candida utilis-Saccharomyces cerevisiae hybrid.
Meiotic segregants derived from a Candida utilis--Saccharomyces cerevisiae hybrid obtained by protoplast fusion were crossed to several standard S. cerevisiae laboratory strains. Random spore and tetrad analysis suggested that in these segregants, karyogamy is impaired and internuclear chromosome transfer occurs.
