During meiosis, at which stage do sister chromatids separate from each other?
A
Metaphase II
B
Anaphase II
C
Anaphase I
D
Prophase I
Verified step by step guidance1
Recall the two divisions of meiosis: Meiosis I and Meiosis II. Each has distinct stages where chromosomes behave differently.
Understand that during Meiosis I, homologous chromosomes separate, but sister chromatids remain together. This separation happens in Anaphase I.
In Meiosis II, the sister chromatids finally separate. This is analogous to mitosis, where chromatids are pulled apart.
Identify the specific stage in Meiosis II when sister chromatids separate: it is during Anaphase II, when the spindle fibers pull the chromatids toward opposite poles.
Confirm that Metaphase II is when sister chromatids line up at the metaphase plate, and Prophase I is an earlier stage where homologous chromosomes pair up and crossing over occurs.
