Detailed explanation-1: -The sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell.

Detailed explanation-2: -Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate.

Detailed explanation-3: -At the end of anaphase I, two haploid sets are present at each end of the cell. Because of these factors, the centromeres do not split during anaphase I.

Detailed explanation-4: -The splitting of centromere does not occur in anaphase I but occurs in anaphase II. Anaphase is the stage of mitosis or meiosis when chromosomes are split and the sister chromatids move to opposite poles of the cell.

Detailed explanation-5: -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.
