Anaphase I involves which event?

Explanation:
Anaphase I is the stage of meiosis when homologous chromosomes are pulled apart to opposite poles. The sister chromatids stay attached at their centromeres, so the separation occurs between homologous chromosomes rather than between sisters. This separation of homologs halves the chromosome number in the daughter cells, which is a defining feature of meiosis I. DNA replication already happened earlier in S phase, so it’s not occurring here. The cell will not divide into four cells until after meiosis II and cytokinesis. Also, sister chromatids separate in a later stage (anaphase II), not during anaphase I.
