Meiosis and Its Significance · NCERT Biology

During Anaphase II, what happens to the sister chromatids?

  1. They remain attached at the centromere
  2. They split and move to opposite poles
  3. They pair with homologous partners
  4. They undergo crossing over
Show answer and explanation

Correct answer: They split and move to opposite poles

Anaphase II involves the simultaneous splitting of the centromere of each chromosome. This allows the sister chromatids to move toward opposite poles of the cell.
