Meiosis I is reductional division. Meiosis II is equational division due to

1. pairing of homologous chromosomes
2. crossing over
3. separation of chromatids
4. disjunction of homologous chromosomes

Correct answer: separation of chromatids

Solution

Meiosis I is reductional because homologous chromosomes separate, halving the chromosome number. Meiosis II is equational because sister chromatids separate, so the chromosome number remains unchanged in each daughter cell.
