Copies of chromosomes linked together at their centromeres at the beginning of meiosis are called ____ chromatids.

Question

Quizplus · Accepted Answer

Chromosomes are duplicated during the S phase of interphase, resulting in the formation of sister chromatids that are held together at their centromeres. During meiosis, homologous chromosomes pair up and undergo crossing over, but the sister chromatids still remain linked at their centromeres until they are pulled apart during anaphase II. Therefore, the correct term for this stage of meiosis is "sister chromatids."
