Electron micrographs have shown that the bisexual forms of Chlamydozyma spp. have a single nucleus. Thus segregation of chromosomes may occur at haploidizatlon when the bisexual produces unisexual offspring. Dr. El-Anl''s contention that protosexual yeasts are basically ascosporogenous is refuted by the fact that ascospores are never observed, although the entire sexual cycle occurs in the laboratory. If ascospore formation were genetically blocked, the entire cycle could not occur.
