Options

  1. A(A)-(I), (B)-(III), (C)-(II), (D)-(IV)
  2. B(A)-(III), (B)-(II), (C)-(I), (D)-(IV)
  3. C(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
  4. D(A)-(III), (B)-(I), (C)-(II), (D)-(IV)

Correct answer

D. (A)-(III), (B)-(I), (C)-(II), (D)-(IV)

Step-by-step solution

Splitting of the centromere and separation of sister chromatids occurs during Anaphase II of meiosis (as well as mitotic anaphase). Separation of homologous chromosomes occurs during Anaphase I of meiosis, while the sister chromatids remain associated at their centromeres. Alignment of bivalents (homologous chromosome pairs) on the equatorial plate takes place during Metaphase I. Condensation of chromosomal material (chromatin) into distinct chromosomes is the characteristic event of Prophase. Therefore, the correc
