Meiosis
Multiple Choice
During meiosis, how many times does the cell progress through the stages of PMAT (prophase, metaphase, anaphase, telophase) to complete division?
A
Once, because meiosis produces four cells in a single division.
B
Four times, because PMAT occurs once for each of the four haploid products.
C
Twice, because meiosis consists of two successive divisions (meiosis I and meiosis II).
D
Three times, because crossing over adds an extra division cycle.
Verified step by step guidance1
Recall that meiosis is a type of cell division that reduces the chromosome number by half, producing four haploid cells from one diploid cell.
Understand that meiosis consists of two distinct rounds of division, called meiosis I and meiosis II, each with its own stages of prophase, metaphase, anaphase, and telophase (PMAT).
Recognize that during meiosis I, homologous chromosomes separate, and during meiosis II, sister chromatids separate, which is why two rounds of PMAT occur.
Note that crossing over happens during prophase I but does not add an extra division cycle; it is a process within the first prophase stage.
Conclude that the cell progresses through the stages of PMAT twice to complete meiosis, once in meiosis I and once in meiosis II.
