mating type

A term which, in lower organisms, is equivalent to sex (male, female). In many species of microorganisms, individuals can be divided into two types; mating can take place only between individuals of opposite mating types due to the interaction of cell surface components. Mating types differ physiologically, but not always physically.

To further confirm that IUM 99-3617 was MATa in mating type, MFa and STE 20a genes were sequenced by an ABI PRISM 310 automatic sequencer using Big Dye Terminator (Applied Biosystems, Monza, Italy) and the primers, forward and reverse strands previously reported (4).

In yeasts, which come in two "mating types" (scientists don't refer to them as "male" and "female"), imprinting clearly serves to ensure that only yeast cells of opposite mating types can go on to reproduce.
However, they also possess a bipolar mating system, with mating types a or [alpha].
