Identify the meiotic stage in which the homologous chromosomes separate while the sister chromatids remain associated at their centromeres
  1. metaphase-I
  2. metaphase-II
  3. anaphase-I
  4. anaphase-II

Solution

In anaphase-I of meiosis homologous chromosomes separate and pass towards different poles of the spindle creating two haploid sets of chromosomes. During anaphase-II of meiosis centromere of two chromatids of a chromosome separate. The separated chromatids become independent daughter chromosome.
