Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When do sister chromatids separate during Meiosis?
A
Metaphase I
B
Metaphase II
C
Anaphase I
D
Anaphase II
Explanation: 

Detailed explanation-1: -Sister chromatids separate during anaphase in a three-stage program as directed by interaxis bridges.

Detailed explanation-2: -Anaphase II: During anaphase II, the centromere splits, freeing the sister chromatids from each other. At this point, spindle fibers begin to shorten, pulling the newly-separated sister chromatids towards opposite ends of the cell.

Detailed explanation-3: -Anaphase II is the stage when sister chromatids of every chromosome separate and begin to move towards the opposite ends of the cell. The separation and the movement is due to the shortening of the kinetochore microtubules.

Detailed explanation-4: -During anaphase II, microtubules from each spindle attach to each sister chromatid at the kinetochore. The sister chromatids then separate, and the microtubules pull them to opposite poles of the cell.

Detailed explanation-5: -Sister chromatids separate during anaphase in a three-stage program as directed by interaxis bridges.
