That's how crossing over works. I believe it's first mentioned in biology class around grade 7.

To be fair, it is possible that for a lot of people this is the last time it is ever mentioned too. Despire being Ms in biological sciences, not sure I've heard it after high school. Or maybe it just didn't draw my attention since I still remembered it.
