Responses

Homologous chromatids are divided in half and distributed randomly into new diploid cells.
Homologous chromatids are divided in half and distributed randomly into new diploid cells.

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

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 definition accurately reflects the mechanism of crossing over during meiosis, where homologous chromosomes (not chromatids) align and exchange segments of genetic material between non-sister chromatids.
