C. Crossing over
D. Hybridization
Answer: Option C
Solution(By Examveda Team)
An exchange of genetic material between homologous chromosomes is called Crossing over.crossing over is the exchange of genetic material during sexual reproduction between two homologous chromosome's non-sister chromatids that results in recombinant chromosomes.
It is one of the final phases of genetic recombination, which occurs in the pachytene stage of prophase I of meiosis during a process called synapsis.
The linked frequency of crossing over between two gene loci (markers) is the crossing-over value.
