Crossing-over involves the exchange of genetic information between

A. chromatids.

B. sex chromosomes.

C. sister chromatids.

D. homologues.

The answer for the question is; the sex chromosomes. Cross over is a process that take place during prophase I of meiosis I, the first phase of meiosis. In this stage the replicated homologous chromosomes pair up with each other and exchange different segment of their genetic materials to form what we call recombinant chromosomes. This process enhances genetic variation among organisms
