Question

Quizplus · Accepted Answer

Saccharomyces cerevisiae produces haploid cells of two mating types that are morphologically similar, and cells of opposite mating types can mate. This is a characteristic of an isogamous species. Heterogamous species have morphologically different gametes, which are necessary for sexual reproduction. Prokaryotic species do not have a nucleus or other membrane-bound organelles, and asexual reproduction involves only one parent, producing genetically identical offspring.
