During which of the following stages of cell division do homologous chromosomes separate, while sister chromatids remain associated at their centromeres?

Options

  1. AAnaphase of mitosis
  2. BAnaphase II of meiosis
  3. CAnaphase I of meiosis
  4. DMetaphase I of meiosis

Correct answer

C. Anaphase I of meiosis

Step-by-step solution

In Anaphase I of meiosis, the homologous chromosomes separate, while sister chromatids remain associated at their centromeres. In contrast, during Anaphase of mitosis and Anaphase II of meiosis, the centromeres split and sister chromatids separate and move towards opposite poles. Metaphase I involves the alignment of bivalents at the equatorial plate, not their separation. Answer: Anaphase I of meiosis
