Definitions for "Mating type"
A homokaryotic haploid stage that will produce a diploid or dikaryotic stage only after pairing with a compatible mating type.
The equivalent of male and female for a eukaryotic microorganism.
The sex of a yeast cell. In S. cerevisiae three types of cells can be distinguished: , alpha and /alpha. The haploid and alpha cells can mate with each other. During mating, cellular and nuclear fusion of the two cells of opposite mating type occurs, forming the third cell type, the diploid /alpha cell. The /alpha cell cannot mate but, unlike and alpha cells, can be induced by external signals to enter meiosis and undergo sporulation.
