 When genes are located on the same chromosome, they may be separated by recombination during the process of meiosis. The frequency at which this occurs is referred to as recombination frequency. In the given scenario, genes A and B are located on the same chromosome, but they show a recombination frequency of 10%. This indicates that these genes are not tightly linked, and some crossing over events have occurred during meiosis, resulting in separation of the two genes. Thus, the type of linkage that exists between genes A and B is incomplete linkage.

Option  2  is the correct answer.
