Detailed explanation-1: -This statement is true. DNA replication occurs in interphase before the first meiotic cycle occurs. The first meiotic division will yield two daughter cells which will then undergo another round of meiotic division producing two more daughter cells.

Detailed explanation-2: -Interphase doesn’t occur a second time because after the first division of meiosis the cell only contains half the chromosomes necessary to perform its functions.

Detailed explanation-3: -Common mistakes and misconceptions. Interphase is not part of meiosis. Although a cell needs to undergo interphase before entering meiosis, interphase is technically not part of meiosis. Crossing over occurs only during prophase I.

Detailed explanation-4: -Answer and Explanation: The correct answer is b. 1. Interphase is not a part of meiosis rather it is a preparation process of the cell before division.

Detailed explanation-5: -In meiosis, a single cell divides twice to produce four daughter cells. These daughter cells or sex cells have exactly half the genetic material of normal gametes. Meiosis necessitates two divisions since it produces a haploid cell with half the amount of chromosomes. Thus meiosis occurs twice.
