Answer :
Meiosis occurs normally 3 only. In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes.
In sexually reproducing organisms, meiosis is a unique type of cell division of germ cells that results in the production of gametes, such as sperm or egg cells. It comprises two rounds of division, producing four cells with only one copy of each chromosome as a final product (haploid). Additionally, each chromosome undergoes genetic material cross-pollination between the paternal and maternal copies before division, resulting in novel combinations of the genetic code on each chromosome. Later, when a male and a female go through meiosis, the haploid cells they generate unite to form the zygote, another cell with two copies of each chromosome. The most common genetic cause of developmental problems and the primary known cause of miscarriage are errors in meiosis that result in aneuploidy (an incorrect number of chromosomes).
