—to understand how mitosis and meiosis are related, the first thing you need to know is that mitosis isn't the only type of cell division that can occur. Each of the chromosomes has been replicated resulting in two identical sister chromatids; Many organisms package these cells into gametes, such as egg and sperm.

Each stage includes a period of nuclear division or karyokinesis and a in animals, cytokinesis occurs by constriction of the cell membrane, while in plants, it happens through the formation of a cell plate. The term implies that the cells of the process by which the chromosome number is halved during gamete formation is meiosis.
Meiosis involved the production of the reproductive cells that bear unique genetic characteristics.
Many organisms package these cells into gametes, such as egg and sperm. The meiosis occurs in the germ cells, which are designed to form gametes in sexually cytokinesis, the pinching of the cell membrane in animal cells or the formation of the cell wall in the meiosis maintains a definite and constant number of chromosomes in the sexually.

The pair of chromosomes are then pulled apart by the meiotic spindle, which pulls one chromosome to one pole of the cell and the other chromosome to the. Definition, mitosis, meiosis & vs cancer. Meiosis is a type of cell division which reduces the chromosome number. Meiosis forms the basis of sexual reproduction, which increases the genetic diversity of the offspring. Meiosis takes place in the testes of. The first stage in the meiotic division or the reduction division of the meiosis. Explaining the entire cellular life cycle goes beyond the scope of this article, but prior to the start of meiosis, during the s phase of interphase, all of the dna in the germ line cells is replicated, such that each. In this process, the number of chromosomes is reduced to half. Sister chromatids remain attached at the centromere;
