Lampbrush chromosomes occur during

1. prophase of mitosis
2. diplotene of meiosis
3. metaphase of meiosis
4. interphase

Correct answer: diplotene of meiosis

Solution

Lampbrush chromosomes are characteristic of the diplotene stage of prophase I in meiosis, especially in growing oocytes. At this stage, homologous chromosomes begin to separate but stay connected at chiasmata, and the chromosomes become highly extended and active in RNA synthesis.
