D

prophase - II

Text Solution

Verified by Experts

The correct Answer is:
C

The pachytene stage of prophase-I of meiosis - I is characterised by the appearance of recombination nodules, the sites at which crossing over occurs between non-sister chromatids of the homologous chromosomes. Crossing over is the exchange of genetic material between two homologous chromosomes. It is also an enzyme mediated process and the enzyme involved is called recombinase.
