Diploid cells. Meiosis is the process of cell division by
which involving gametes. Cell division is just the same for sperm and egg
cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis
is for the males’ sperm cells and oogenesis is the process for females’ egg
cells. The cell division of meiosis involves the two phases, respectively
meiosis I and meiosis II. Meiosis I like mitosis is the cell division that
produces diploid cells. These diploid cells are cells that contain a complete
pair of chromosomes which is 46. The result is two diploid cells after the
first meiosis. To provide clear explanation, in contrast haploid cells only
contain 23 chromosomes and are created after meiosis II which is 4 in number.
