Detailed explanation-1: -There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced.

Detailed explanation-2: -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.

Detailed explanation-3: -These goals are accomplished in meiosis using a two-step division process. Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis II.

Detailed explanation-4: -In meiosis I these are known as prophase I, metaphase I, anaphase I and telophase I, while in meiosis II they are known as prophase II, metaphase II, anaphase II and telophase II. Different products are formed by these phases, although the basic principles of each are the same.

Detailed explanation-5: -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.
