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 where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in … WebThe mitotic and meiotic cell cycles (A) In mitosis, diploid cells replicate chromosomes during S phase and segregate sister chromatids during M phase, so that diploid daughter cells are produced. (B) In meiosis, two chromosome-segregation phases, meiosis I and meiosis II, follow a single round of DNA replication during the premeiotic S phase. synchrony bank legal department contact
