WebMar 26, 2024 · It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells. When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46. Meiosis also allows genetic variation through a process of gene shuffling while the cells are dividing. WebSep 13, 2024 · A single gametophyte moss plant can produce both sperm and eggs. This can occur on different parts of the same plant, one part producing sperm and another part producing eggs. However, a plant usually produces either all sperm-producing organs or all egg-producing organs at any one time. lionel goldstein halpern johnson
