Periodically, meiosis produces morphologically identical haploid gametes (isogametes), which fuse to produce a (sometimes binucleate) zygote that develops into an auxospore (from which full-sized vegetative cells are produced).
Meiosis regularly yields morphologically identical haploid gametes (isogametes) that unite to produce a zygote, which then develops into an auxospore from which full-sized vegetative cells are produced.
