Question

which correctly describes crossing over? the process whereby non - sister chromatids exchange genetic material the process whereby homologous chromosomes are pulled to opposite poles of the cell the process whereby sister chromatids are pulled to opposite poles of the cell the process whereby homologous chromosome pairs align randomly along the metaphase plate

Explanation:

Crossing - over occurs during meiosis when non - sister chromatids exchange genetic material. This process increases genetic diversity. The other options describe different events in meiosis such as independent assortment (homologous chromosome pairs align randomly along the metaphase plate), anaphase II (sister chromatids are pulled to opposite poles of the cell), and anaphase I (homologous chromosomes are pulled to opposite poles of the cell).

Answer:

The process whereby non - sister chromatids exchange genetic material
