WebJun 17, 2024 · Half of these chromosomes are inherited from the father's gamete (sperm) and a half from the mother gamete (egg) to make a normal, diploid, individual that contains 46 total chromosomes. WebApr 6, 2024 · On fertilizing with a haploid female gamete, diploidy is restored. Tetrad is a four nucleated cell. A microspore tetrad is a cluster of male gametes formed by the microsporogenesis. Meiosis1 occurs in the microspore mother cell which produces 2 diploid cells. After the meiosis2 the number of cells becomes four.
