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 males, eggs in females. Meiosis in humans happens before birth in females, and constantly after puberty in males. WebFinally, unlike mitosis, meiosis involves two rounds of nuclear division, not just one. Despite this fact, many of the other events of meiosis are similar to those that occur in mitosis.

WebMeiosis How many daughter cells are produced in meiosis? Four Describe the daughter cells of a parent cell which underwent meiosis. The daughter cells (four) are genetically different from themselves and their parent, they are haploid (n), they have 23 chromosomes, and they are categorized as gametes, or sex cells. WebIn one meiotic division, one megaspore mother cell produces one female gamete (4 produce, 3 degenerated). For the production of 400 female gametes, the number of meiotic division is 400. So, the total number of meiotic divisions are 100+400=500. Thus, the correct answer is option B.
