WebSep 4, 2024 · Crossing-over occurs during prophase I, and it is the exchange of genetic material between non-sister chromatids of homologous chromosomes. Recall during prophase I, homologous chromosomes line up in pairs, gene-for-gene down their entire length, forming a configuration with four chromatids, known as a tetrad. 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.
