WebChlamydomonas reinhardtii is a unicellular volvocine alga having two mating types: mating type plus (mt+) and mating type minus (mt-), which are controlled by a single, complex mating-type locus. Sexual adhesion between the gametes is mediated by sex-specific agglutinin molecules on their flagellar membranes.
WebChlamydomonas is considered a volvocine algae, a class of algae comprised of several species of increasingly complex multicellularity.
