Question

the exchange of genetic material between nonsister chromatids is called crossing - over and occurs during which phase of meiosis? multiple choice prophase ii metaphase i interphase

Explanation:

Cross - over occurs during prophase I of meiosis when homologous chromosomes pair up and exchange genetic material between non - sister chromatids. It does not occur in prophase II (no homologous pairing for crossing - over then), metaphase I (chromosomes are aligned at the equator), or interphase (chromosomes are in a non - paired, non - crossing - over state).

Answer:

None of the provided options are correct. The correct phase is prophase I.
