_________________☺️☺️☺️☺️

Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division). Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. ... Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).

In single celled organisms cell reproduction gives rise to the next generation. In multicellular organisms cell division occurs not just to produce a whole new organism but for growth and replacement of worn out cells within the organisms. Cell division is always highly regulated and follows a highly orchestrated series of steps. The term cytokinesis refers to dividing a cell in half, while mitosis and meiosis refer to two different forms of nuclear division. Mitosis results in two nuclei that are identical to the original nucleus. Meiosis on the other hand results in four nuclei that each have ½ the chromosomes of the original cell. In animals meiosis only occurs in the cells that give rise to the sex cells (gametes), i.e., the egg and the sperm.
