Web5 apr. 2024 · The main difference between mitosis and meiosis is that mitosis is the equational division which means that the cell divides into two equal daughter cells. Meiosis is known as the reductional division. Meiosis normally occurs in the gamete cell. In meiosis cells, genetic material reduces to half (2n ⇢ n). Web1 mrt. 2024 · Mitosis differs from meiosis in that meiosis is the production of gametes, or sex cells, which will allow for genetic recombination in sexual organisms. However, without mitosis, the embryos formed will never grow to become organisms. Mitosis is preceded by DNA replication, to form two diploid sets of chromosomes. Mitosis has five phases.
