WebMeiosis employs many of the same mechanisms as mitosis. However, the starting nucleus is always diploid and the nuclei that result at the end of a meiotic cell division are haploid. To achieve this reduction in chromosome number, meiosis consists of one round of chromosome duplication and two rounds of nuclear division. WebSep 4, 2024 · You want all your new cells to have the same DNA as the previous cells. The goal of meiosis is to produce sperm or eggs, also known as gametes. The resulting gametes are not genetically identical to the parent cell. Gametes are haploid cells, with only half the DNA present in the diploid parent cell. WebMitosis and meiosis have several major differences. In many ways, meiosis is similar to mitosis, but there are some important differences. These differences stem from the function of each type of cell division. The function of mitosis is to produce two genetically identical cells.
