Q.

The process of appearance of recombination nodules occurs at which sub stage of prophase I in meiosis?

  1. A

    Zygotene

  2. B

    Pachytene

  3. C

    Diplotene

  4. D

    Diakinesis

Solution

Recombination nodules — protein complexes that mediate crossing over between non-sister chromatids of homologous chromosomes — appear during pachytene. Synapsis is completed in zygotene; the chiasmata become visible in diplotene; terminalisation occurs in diakinesis.
