Worked practice questions

The short stage between the two meiotic divisions is called what?

  1. Diakinesis
  2. Cytokinesis
  3. Interkinesis
  4. Karyokinesis
Show answer and solution

Correct answer: C. Interkinesis

Interkinesis is the generally short-lived gap between meiosis I and meiosis II.

Meiosis II most closely resembles which process?

  1. Normal mitosis
  2. Meiosis I
  3. Binary fission
  4. Amitosis
Show answer and solution

Correct answer: A. Normal mitosis

Meiosis II separates sister chromatids just as an ordinary mitosis does.

Which event starts anaphase II of meiosis?

  1. Homologues move apart
  2. Centromeres split
  3. Chiasmata terminalise
  4. Synapsis begins
Show answer and solution

Correct answer: B. Centromeres split

Anaphase II begins when each centromere splits, freeing sister chromatids to move to opposite poles.
