Crossing-over involves the exchange of genetic information between

Achromatids.
Bsex chromosomes.
Csister chromatids.
Dhomologues.

Verified Answer :

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

Answer: Homologous

Explanation: The crossing over can be defined as the exchange of genetic material between homologous non-sister chromatids during sexual reproduction.

Homologous chromosomes represent a pair of chromosome in which each chromosome is derived from one parent.It takes place during pachytene stage of meiosis I, by a process known as synapses.
