WebMitosis creates two identical daughter cells that each contain the same number of … WebMitosis refers to the splitting of chromosomes in the eukaryotic cells during the cell division process. The parent cell divides into two daughter cells that are identical to the parent cell during the process of cell division. During the mitosis process, the cell’s nucleus along with the chromosome is divided to form two new daughter cell nuclei.
