Answer 1

The statement that best describes the process of crossing over is:

Homologous chromosomes pair up, and non-sister chromatids exchange genetic material.

This accurately reflects the mechanism of crossing over during meiosis, where homologous chromosomes align and exchange segments, resulting in increased genetic diversity.
