To understand the relevance of crossing over in chromosome division, it's important to consider the processes of meiosis and mitosis:

1. **Definition of Crossing Over**: This is a process that occurs during prophase I of meiosis where homologous chromosomes exchange genetic material, leading to genetic variation.

2. **Meiosis**: This is the type of cell division involved in sexual reproduction, where crossing over occurs. It leads to gamete formation (sperm and egg cells) and results in four genetically diverse cells.

3. **Mitosis**: This is the type of cell division that results in two genetically identical daughter cells. It is primarily for growth and repair, and it does not involve crossing over.

### Conclusion:
Crossing over occurs only in meiosis, hence the correct answer is: **meiosis only**.
