a process of shift-down or reduction of ploidy from tetraploid to diploid was also observed by electron microscopy during these growth conditions : this appeared to occur in large cells which showed multiple spindle formation during nuclear division , a phenomenon apparently similar to the process of meiosis ii during sporogenesis of saccharomyces cerevisiae , but differing in that it produces diploid daughter nuclei by the vegetative process .
