Question

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

• A. Diakinesis
• B. Zygotene
• C. Pachytene
• D. Diplotene

Answer 1

Answer:

C. Pachytene

• The process of the appearance of recombination nodules occurs during the Pachytene sub-stage of prophase I in meiosis.

• After zygotene comes the pachytene stage. This stage is characterised by the appearence of recombination nodules at which crossing over occurs between non-sister chromatids of the homologous chromosomes.
