saccharomyces cerivisae is a very interesting organism. It is part of the Endomycetales order and reproduces both asexually and sexually.
Asexual reproduction: These fungi do not create asexual ascospores. through budding(not sure about translation though...). The fungus forms asces with 4 ascospores
Sexual reproduction: In those asces 4 ascospores develop, each having n=4 chromosoms as opposed to the vegetative fungus that has 2n=8. THESE ARE SEXUAL SPORES, WITH DIFFERENT SEXUAL POTENTIALS(you can call them gamets, but, for some reason, the people that write fungi biosistematics books prefer the sexual spores term). After copulation, these spores form a new diploid organism...
