Answer:

The correct answer is - prophase I

Explanation:

Crossing over or recombination is the event that takes place during the pachytene stage of Prophase I of Meiosis I. During this event, the exchange in genetic material between non-sister chromatids of homologous chromosomes results in the recombination of the genetic material or recombinant chromosome.

Prophase I is the first stage which is characterized by the condensation of the chromosome and form tetrad and appeared to be X like structure in the cell and followed by the crossing over or genetic exchange of homologous chromosomes.
