Abstract excerpt
In the yeast Saccharomyces cerevisiae, only a/alpha cells can enter meiosis; a and alpha cells cannot. Because a/alpha cells are typically diploid and a and alpha cells are typically haploid, this cell type restriction ensures that only diploid cells enter meiosis. Entry into meiosis is accompanied by an increase in expression of the IME1 gene; the IME1 product (IME1) then activates IME2 and other meiotic genes....
