Crossing-Over is a process that occurs in prophase 1 of meiosis.

Explanation:

In prophase 1, pairs of homologous chromosomes line up side by side, otherwise known as tetrads. When they are lined up, segments of chromosomes are exchanged. This process is also known as crossing-over. This process of exchange of genetic information is an important mechanism as it provides genetic variation and a random genetic draw to diversity. enter image source here
