Crossing over is when homologous chromosomes exchange genetic material during Prophase I (Meiosis). Crossing over is one of a couple things that leads to genetic variation.

Independent assortment is one kind of genetic, one where the chromosomes supplied by one's
parents are literally
independently assorted into resulting gametes. |
