Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
At which stage of meiosis are sister chromatids separated from each other?
A
prophase I
B
prophase II
C
anaphase I
D
anaphase II
Explanation: 

Detailed explanation-1: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.

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 third stage in meiosis II. It is the stage after metaphase II, which is that phase wherein the chromosomes are at the equatorial plane and spindle fibers are attached to the kinetochores.

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: -During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes.
