During meiosis I, the chromosomes start pairing at

1. Leptotene
2. Zygotene
3. Pachytene
4. Diplotene

Correct answer: Zygotene

Solution

In meiosis I, homologous chromosomes begin pairing during zygotene, when synapsis starts. Leptotene is mainly chromosome condensation, while pachytene and diplotene occur after pairing has already begun.
