Question

crossing - over takes place between...
sister chromatids
analogous chromosomes
homologous chromosomes
rewatch

Explanation:

Crossing-over is a genetic event in meiosis where genetic material is exchanged between non-sister chromatids of chromosome pairs that carry the same genes (one from each parent). Sister chromatids are identical copies of a single chromosome, so no genetic recombination occurs between them. "Analogous chromosomes" is not a standard term for this process.

Answer:

homologous chromosomes
