How many times does each stage of PMAT occur in meiosis?
A
1
B
2
C
3
D
4
Explanation: 

Detailed explanation-1: -The Phases of Meiosis II Meiosis II is known as equational division, as the cells begin as haploid cells and end as haploid cells. There are again four phases in meiosis II: these differ slightly from those in meiosis I.

Detailed explanation-2: -Meiosis does PMAT twice! That means there is a prophase I and a prophase II.

Detailed explanation-3: -In meiosis II, the phases are, again, analogous to mitosis: prophase II, metaphase II, anaphase II, and telophase II (see figure below).

Detailed explanation-4: -Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice-once during the first round of division, called meiosis I, and again during the second round of division, called meiosis II.
