WebSep 5, 2024 · Mitosis is the process by which most cells in the body divide, involves a single round of cell division, and produces two identical, diploid daughter cells. Meiosis is the process by which gametes are produced. Meiosis involves two rounds of cell division and produces four non-identical haploid daughter cells. WebMitosis produces two daughter cells that are genetically identical to each other, and to the parental cell. A diploid cell starts with 2N chromosomes and 2X DNA content. After DNA replication, the cells is still genetically diploid (2N chromosome number), but has 4X DNA content because each chromosome has replicated its DNA. greg abbott building wall https://paulwhyle.com
