Answer:
The genes, which are situated in close proximity on a chromosome exhibits a greater linkage tendency. This signifies that it is very much possible that these genes are going to be transmitted together to the next generation. In contrast, the genes, which are found on different chromosomes exhibit a slight chance to be passed on together. Thus, the unlinked genes are the genes present on different chromosomes, the not so strong linked genes are the genes that are far from each other, but on the similar chromosome, and the strongly linked genes are the genes close to each other.
