WebMeiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote. What happens between these two events, however, can differ a lot between different organisms—say, between you and a mushroom or oak tree! There are three main categories of sexual life cycles.
