Detailed explanation-1: -In anaphase I, the homologues are pulled apart and move apart to opposite ends of the cell. The sister chromatids of each chromosome, however, remain attached to one another and don’t come apart. Finally, in telophase I, the chromosomes arrive at opposite poles of the cell.

Detailed explanation-2: -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.

Detailed explanation-3: -Anaphase I: In anaphase I, the attachment of the spindle fibers is complete. The homologous chromosomes are pulled apart and move towards opposite ends of the cell.

Detailed explanation-4: -The chromosomes are separated by a structure called the mitotic spindle. The mitotic spindle is made of many long proteins called microtubules, which are attached to a chromosome at one end and to the pole of a cell at the other end. The sister chromatids are separated simultaneously at their centromeres.

Detailed explanation-5: -Next, during anaphase, the chromosomes are simultaneously separated and pulled by the spindle to opposite poles of the cell.
