During metaphase I the paternal and maternal chromosomes line up at the equtor, and the homologous ones pair up. Two parts of the chromosomes, one paternal and one maternal join at a point called chiasmata.They both break at this point and the cut pieces are exchanged, i.e, the maternal cut goes to the paternal chromosome and vice versa.
