Sample Problem

Label the following “I” or “II” to indicate whether they occur in Meiosis I or Meiosis II, respectively.

sister chromatids separate

homologous chromosome separate

synapsis occurs

produces haploid cells

crossing-over occurs

Solution

The answers are as follows: II, I, I, II, I. Synapsis and crossing-over occurs, then the homologous chromosome separate in Meiosis I. In Meiosis II, the sister chromatids separate to produce 4 different haploid cells.
