WebMitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes. WebFour haploid daughter cells are produced at the end, unlike two diploid daughter cells in mitosis. Meiosis 1 separates the pair of homologous chromosomes and reduces the diploid cell to haploid. It is divided into …
