Meiosis and Its Significance · NCERT Biology

Meiosis II is often compared to mitosis because:

  1. Homologous chromosomes pair and undergo synapsis
  2. The chromosome number is reduced from 2n to n
  3. Sister chromatids separate at the centromere
  4. Crossing over between non-sister chromatids occurs
Show answer and explanation

Correct answer: Sister chromatids separate at the centromere

Meiosis II is an equational division, mirroring mitosis: the centromere of each chromosome splits and sister chromatids move to opposite poles. This ensures each of the four final gametes receives one chromatid from each chromosome.
