Hello Student,

Pachytene stage is a part of Prophase I of Meiosis I.

Features of Pachytene Stage in Cell Divison are as follows :

• It is the longest stage of Prophase I
• Bivalents are more clearly visible
• Recombination starts between non-sister chromatids of homologous chromosomes
• Crossing over is mediated in this phase by recombinase enzyme
• Recombination nodules appear at crossing over sites
• Recombination is complete is this phase

Hope this Helps
