WebNov 18, 2024 · Meiosis. Meiosis describes the process of cell division by which gametes are made. In this process, we begin with a cell with double the normal amount of DNA, and end up with 4 non-identical haploid daughter gametes after two divisions. There are six stages within each of the divisions, namely prophase, prometaphase, metaphase, … WebMitosis and meiosis are both forms of division of the nucleus in eukaryotic cells. They share some similarities, but also exhibit distinct differences that lead to very different outcomes. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new cells. ecslimited shop https://jackiedennis.com
