what would have happened if meiosis not occur during the production of human sperm cell and Egg cell?
Answers
Mitosis allows us to make more of our body's somatic cells to grow, develop, and repair injuries.
During mitosis, all the chromosomes in a cell are copied, line up at the metaphase plate, split apart at the centromere, and segregate into two new (but genetically identical) cells...
Mitosis results in the formation of diploid cells, i.e. (in humans) each daughter cell would have 23 pairs of homologous chromosomes, or 46 chromosomes total. Meiosis results in the formation of haploid cells, i.e. each daughter cell would have only 23 total chromosomes, none of which are in a homologous pair.
If gametes (sperm and egg) were made by mitosis, then they would be diploid. If a diploid sperm fused with a diploid egg, then the resulting zygote would be tetraploid (46 pairs of chromosomes, or 92 chromosomes total). A tetraploid zygote is not viable and will most likely miscarriage.
