**Step-by-Step Solution:** 1. **Understanding Chromatids**: Begin by identifying the types of chromatids involved in the process. Non-sister chromatids are found in homologous chromosomes, which consist of one chromosome from the mother and one from the father. 2. **Definition of Crossing Over**: The exchange of genetic material between non-sister chromatids occurs during a specific phase of meiosis. This process is known as "crossing over." 3. **Mechanism of Crossing Over**: During meiosis, homologous chromosomes pair up and align closely. This alignment allows for segments of DNA to be exchanged between the non-sister chromatids. ...
