mitosis (division of the cell nucleus) and cytokinesis (division of the cytoplasm)
In eukaryotic cells: the two main stages are:
-The duplication of DNA in the S phase (interphase)
-Separation of sister chromatids during anaphase (mitosis)
Meiosis involves two divisions in its process.
It is called spermatogenesis and for females it is called oogenesis.
The two meiotic divisions are called meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing-over before separating, resulting in two daughter cells with half the number of chromosomes as the parent cell. In meiosis II, sister chromatids separate, resulting in four daughter cells, each with a unique combination of genes.
The meiosis of egg formation is called oogenesis. During oogenesis, a primary oocyte undergoes two divisions to produce a single mature egg cell.
Even if there was that kind of sex cell, I don't think it would survive! Sex cells ALWAYS have 46 chromosomes. At the end of meiosis, as long as there are no mistakes, each sperm or egg cell would have 23 chromosomes.
There are 2 cell divisions in meiosis.

meiosis
It is called spermatogenesis and for females it is called oogenesis.
Meiosis does in fact divide twice, once in meiosis I (cytokinesis) and meiosis II (cytokinesis) basically it divides into four daughter cells at the end of meiosis. Two from meiosis I and four in meiosis II
