Solution
Nondisjunction can occur during both Meiosis I and Meiosis II.
In Meiosis I, nondisjunction can occur if both members of a homologous pair go into the same daughter cell. This results in one daughter cell having two copies of the chromosome and the other daughter cell having no copies.
In Meiosis II, nondisjunction can occur if the sister chromatids do not separate and both daughter chromosomes go into the same gamete. This results in one gamete having two copies of the chromosome and the other gamete having no copies.
So, the correct answer is "Both Meiosis I and II".
