Responses

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

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

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

This accurately describes the exchange of genetic material that occurs during meiosis, where homologous chromosomes align and segments of non-sister chromatids are exchanged, leading to genetic diversity in the resulting gametes.
