Crossing over that results in genetic recombination in higher organisms occurs between:
sister chromatids of a bivalent
non-sister chromatids of a bivalent
two daughter nuclei
two different bivalents.
Solution
Crossing over is the exchange of chromosomal segments between non-sister chromatids of homologous chromosomes during the production of gametes. It occurs during pachytene stage. (Ref. to Fig. 28.4)
