ANATOMY

Detailed explanation-1: -The movement of chromosomes towards opposite poles during Anaphase – I of meiosis is called disjunction.

Detailed explanation-2: -Anaphase. The sister chromatids separate from one another and are pulled towards opposite poles of the cell. The microtubules that are not attached to chromosomes push the two poles of the spindle apart, while the kinetochore microtubules pull the chromosomes towards the poles.

Detailed explanation-3: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell.

Detailed explanation-4: -Chromosomes move poleward in anaphase along stationary microtubules that coordinately disassemble from their kinetochore ends. J Cell Biol (1987) 104 (1): 9–18. During the movement of chromosomes in anaphase, microtubules that extend between the kinetochores and the poles shorten.

Detailed explanation-5: -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.
