WebMitosis 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 ... Webmitosis. produces two genetically identical cells, each with the same number of chromosomes as in the parent. Meiosis begins with a diploid cell, which contains two copies of each chromosome, termed homologs. First, the cell undergoes DNA replication, so each homolog now consists of two identical sister chromatids. dewalt portable miter saw
