Metaphase II

Anaphase I

Anaphase II
|
Explanation:
Detailed explanation-1: -Final answer: During Anaphase I of meotic phase homologous chromosomes separate while the sister chromatids remain associated at their centromeres.
Detailed explanation-2: -During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell.
Detailed explanation-3: -During anaphase I, the homologous chromosome pairs separate and are pulled to opposite poles of the cell by spindle fibers attached to the centrioles. This first cell division process is completed during telophase I.
