Finally, meiosis II takes place, and the sister chromatids are separated into individual … WebCrossing over is the process by which genetic material is exchanged by non-sister chromatids during meiosis. Crossing over results in a new combination of genetic information for the cell for a specific trait. Crossing over ensures that organisms are not identical from generation to generation. WebCrossing over can be observed visually after the exchange as chiasmata (singular = chiasma) (Figure 1).
