Answer:

The correct answer is option b. "The genes share a specific combination of control elements".

Explanation:

Human eye color is an example of a trait that is controlled under the influence of multiple genes (polygenic). Human eye color is mainly determined by the amount of melanin that is present in the front part of the iris, which it is controlled by up to 16 genes. Among the different genes, the ones that mainly influence eye color are: OCA2 and HERC2. These two genes share a specific combination of control elements, for instance, a regulatory element of HERC2 gene inhibits OCA2 expression as well.
