Detailed explanation-1: -Meiosis involves two sequential cycles of nuclear and cell division called meiosis-I and meiosis-II, but only a single cycle of DNA replication.

Detailed explanation-2: -Meiosis is divided into two stages designated by the roman numerals I (one) and II (two). Meiosis I is called a reductional division, because it reduces the number of chromosomes inherited by each of the daughter cells.

Detailed explanation-3: -Mitosis involves one cell division, whereas meiosis involves two cell divisions.

Detailed explanation-4: -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-5: -From LM: Q1 = Cells undergoing mieosis require 2 sets of divisions because only half of the cromosomes from each parent are needed. This is so half of the offspring’s genes come from each parent. This process generates the diversity of all sexually reproducing organisms. Meiosis produces sex cells eggs and sperm.
