Question

Crossing over takes place during which phase of meiosis I?

  1. Prophase I
  2. Metaphase I
  3. Anaphase I
  4. Telophase I

hintHint:

The phase which has substages as follows: leptotene, zygotene, pachytene, diplotene and diakinesis.

The correct answer is: Prophase I


    • Crossing over occurs during prophase 1 of meiosis.
    • Prophase 1 is subdivided into leptotene, zygotene, pachytene, diplotene and diakinesis.
    • During the pachytene stage of prophase 1, crossing over occurs.
    • Crossing over is the process during which the exchange of genetic material between the non-sister chromatids occurs resulting in recombination.
