WebMeiosis occurs in the testes of men and ovaries of women. Meiosis and mitosis differ because: mitosis is a form of cell division which produces two identical, diploid body cells; WebIn meiosis, the starting nucleus is always diploid and the daughter nuclei that result are haploid. To achieve this reduction in chromosome number, meiosis consists of one round of chromosome replication followed by two rounds of nuclear division.
