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: -In meiosis, one diploid cell divides and makes four haploid sex cells. Meiosis occurs only during the formation of sex cells. Meiosis involves two divisions of the nucleus, meiosis I and meiosis II. A reproductive cell goes through interphase before beginning meiosis I.

Detailed explanation-3: -Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell. Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II.

Detailed explanation-4: -Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).

Detailed explanation-5: -Meiosis begins with a diploid cell and ends with four haploid cells. These cells eventually differentiate into mature sperm or egg cells. During meiosis, homologous chromosomes separate, and haploid cells form that have only one chromosome from each pair.
