WitrynaMitosis and meiosis are processes of cell division. In mitosis, a cell divides into two identical daughter cells. During this process, the original parent cell will replicate its genetic material, the chromosomes, and then each chromosome is split into two identical parts. The cell then divides into two daughter cells with the same genetic ...
