Detailed explanation-1: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
Detailed explanation-2: -Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm).
Detailed explanation-3: -There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division, ” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
Detailed explanation-4: -Only sexually reproductive organisms utilize meiosis. The role of the process is to produce sex cells and to repair genetic defects in germ line cells (the sex cells). Both sexual and asexual organisms go through the process of mitosis.
Detailed explanation-5: -Meiosis occurs in the primordial germ cells, cells specified for sexual reproduction and separate from the body’s normal somatic cells. In preparation for meiosis, a germ cell goes through interphase, during which the entire cell (including the genetic material contained in the nucleus) undergoes replication.
