Pairs of homologous chromosomes are divided in half and distributed randomly into new haploid cells

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

Pairs of homologous chromatids are divided in half and distributed randomly into new diploid cells

Answer 1

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

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

Crossing over occurs during meiosis, specifically in prophase I, where homologous chromosomes align and exchange segments of genetic material. This process increases genetic diversity in the resulting gametes.
