| Comments |
Yeasts carrying the "ho" allele are called "heterothallic" meaning that sexes reside in different individuals (with high probability). "Yeast strains differ in the stability of their mating type. In strains carrying the ho allele (“heterothallic” strains), the MATa and MATa alleles are stable during
mitotic growth, with changes from MATa to MATa and
from MATa to MATa observed at low frequency
(~10^-6) (primary sources)." |
