D
Sister chromatids
Verified step by step guidance1
Recall the key events of meiosis, focusing on the stages and what happens during each phase, especially Anaphase I.
Understand that meiosis consists of two divisions: Meiosis I and Meiosis II, each with distinct separation events.
During Anaphase I, homologous chromosomes (each consisting of two sister chromatids) are separated and pulled toward opposite poles of the cell.
Centromeres do not separate during Anaphase I; instead, sister chromatids remain attached at their centromeres until Anaphase II.
Nucleoli are not involved in chromosome separation; they typically disappear during prophase and reappear in telophase.
