Answer:
The correct option is A. They are located close together on the same chromosome.
Explanation:
Linked genes can be described as the genes that are located close together and are always present on the same chromosome. During recombination, these alleles of these genes tend to be inherited together. The space between these genes is so less that the DNA is not cut from between them during the homologous recombination.
For example, the genes of red colour hair and freckles are present very close together. During recombination, the alleles for these genes get inherited together. Hence, a person with red hair is most likely to have freckles.
