AThe sister chromatids only
BThe homologous chromosomes
CThe two centrosomes only
DThe nuclear envelope parts
Answer & Solution
Correct answer: B. The homologous chromosomes
1. In meiosis I the two members of each homologous pair are attached to opposite poles.
2. Anaphase I breaks the chiasmata and drags those homologs apart.
3. Each chromosome that moves is still made of two sister chromatids.
4. Those chromatids stay clamped together at the centromere.
5. They are separated later, in anaphase II, which is a different division.
