Detailed explanation-1: -Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell.

Detailed explanation-2: -Anaphase II involves separation of the sister chromatids.

Detailed explanation-3: -Anaphase II – In this phase of meiosis II, there is a simultaneous splitting of the centromere of each chromosome and the sister chromatids are pulled away towards the opposite poles. As the chromatids move towards the poles, the kinetochore is at the leading edge with the chromosomal arms trailing.

Detailed explanation-4: -In anaphase II, chromosomes divide at the centromeres (like in mitosis) and the resulting chromosomes, each with one chromatid, move toward opposite poles of the cell. Four haploid nuclei (containing chromosomes with single chromatids) are formed in telophase II.

Detailed explanation-5: -During meiosis I, homologous chromosomes, and in meiosis II, sister chromatids are segregated into daughter cells.
