WebDec 30, 2024 · Meiosis generates 4 haploid daughter cells from one diploid precursor. To do so, it undergoes a two rounds of meiotic nuclear and cell division. After a conventional anaphase and telophase, the cell splits, and immediately the daughter cells begin the second meiotic division (Figure 15.8. 18, right side). WebMeiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males).
