Two autosomal genes have a recombination frequency of 16%.Which of the following conclusions can be drawn regarding these genes?
A)The two genes are closely linked on the same chromosome.
B)The two genes are linked but on different chromosomes.
C)Recombination between these two genes cannot occur in the cell during meiosis.
D)The genes are located on the X chromosome.

A recombination frequency of 16% suggests that the genes are linked but not very closely, as a higher recombination frequency would indicate a greater distance between the genes. Therefore, option A is the best choice, as it suggests that the genes are linked but not tightly linked. Option B is not correct because it suggests that the genes are on different chromosomes, which is not consistent with the given recombination frequency. Option C is incorrect because recombination has been observed between these genes, albeit at a low frequency. Option D is also incorrect because the genes are referred to as autosomal, which means they are not located on the X chromosome.
