WebIt is incorrect to state that mitosis has a reduction division step and a separate division step, as mitosis does not involve a reduction division step. Mitosis is a process of cell division in which a parent cell divides into two genetically identical daughter cells, each having the same number of chromosomes as the parent cell. WebMeiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells.

WebSpecifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such ...
