Question

During which phase of meiosis does crossing over chromosomes occur

Answer 1

phase where crossing over chromosomes occur is prophase 1

Answer 2

Pachytene of prophase I of meiosis I

Step-by-step explanation:

Crossing over is the process of exchange of genetic material between non-sister chromatids of homologous chromosomes. It occurs during the pachytene stage of prophase I of meiosis I. During pachytene, the paired homologous chromosomes exchange genetic material between themselves and add new gene combinations to the daughter cells.
