Answer:

Crossing over.

Explanation:

Crossing over is the process of exchange of genetic material between two non-sister chromatids of a homologous chromosome pair. It occurs during pachytene of prophase I of meiosis I. Crossing over creates new gene combinations that were otherwise not present in the parent cells. In this way, genetic variations are created by crossing over.
