WebMeiosis, in contrast, is a unique sort of cell division that only takes place in cells that will develop into gametes. (sperm and egg cells). Meiosis is a two-round cell division process that produces four daughter cells that are genetically unique from both the original parent cell and one another. WebMeiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, …
