Chromosomes contain DNA molecules highly packaged and wound around histone proteins. Each chromosome has two chromatids joined together at a point called centromere. Crossover is a process that take place during meiosis 1 ( first phase of meiosis), it enhances the exchange of genetic material. During cross over the non-sister chromatids of chromosomes fuse at chiasma where exchange of genetic material takes place.Therefore, it will be correct to say that crossover creates sister chromatids that are different, because non-homologous sister chromosomes have swapped genetic material with one another.
