Best answer
Correct answer is (a) True

The best explanation: Genes located on different chromosomes are weakly linked. This allows them to recombine more frequently. Linkage is inversely related to recombination. Genes are located close to each other have low chances of recombination, and thus have high linkage. Genes on different chromosomes are far from each other, hence they have almost no linkage, hence having higher chances of undergoing recombination.
