WebAug 7, 2024 · Both are type of cell division taking place in every eukaryote. But the main difference is Mitosis produces Diploid Somatic cells identical to parent and Meiosis give rise to cells which forms a new progeny which are genetically different from the parent by producing haploid gametes. WebMeiosis only occurs in the testes and ovaries, producing gametes (sperm and egg cells). This is known as reduction division. One diploid cell produces four haploid gametes, in two divisions. Human sex cells contain one chromosome from each of the 23 pairs. The four gametes produced in meiosis are genetically different.
