Detailed explanation-1: -In meiosis, the chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information (chromosomal crossover) during the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes.

Detailed explanation-2: -After Interphase I meiosis I occurs after Interphase I, where proteins are grown in G phase and chromosomes are replicated in S phase. Following this, four phases occur. Meiosis I is known as reductive division, as the cells are reduced from being diploid cells to being haploid cells.

Detailed explanation-3: -For example, prior to undergoing meiosis, a cell goes through an interphase period in which it grows, replicates its chromosomes, and checks all of its systems to ensure that it is ready to divide.

Detailed explanation-4: -Meiosis Consists of a Reduction Division and an Equational Division. Two divisions, meiosis I and meiosis II, are required to produce gametes (Figure 3). Meiosis I is a unique cell division that occurs only in germ cells; meiosis II is similar to a mitotic division.

Detailed explanation-5: -Interphase is not part of meiosis. Although a cell needs to undergo interphase before entering meiosis, interphase is technically not part of meiosis.
