Hello, I'm an expert in genetics and human biology. Let's dive into the topic of eye color and its relation to skin color.

Eye color is determined by variations in a person's genes, and it's particularly influenced by the amount and type of pigments in the front part of the iris, as well as the scattering of light by the turbid medium in the stroma of the iris. While it's more common for people of African descent to have darker eye colors like brown, it's not impossible for a black person to have blue eyes.

The gene responsible for blue eyes is a variant of the OCA2 gene. This gene is involved in the production of melanin, the pigment that gives color to our eyes, skin, and hair. A specific mutation in the OCA2 gene can reduce melanin production in the iris, leading to blue eyes. However, the frequency of this gene variant is much higher in populations of European descent compared to those of African descent.

That said, genetic traits are not strictly determined by skin color. There are many factors that can influence the expression of a trait, including the inheritance of multiple genes and the interaction of genes with the environment. Therefore, while it's less common, it is biologically possible for a black person to have blue eyes.

This photo is, perhaps, the best example of a black African, non-mulatto, non-albino, with blue eyes. Also, the boy in the picture does not appear to have Waardenberg Syndrome, also a source of blue eyes in blacks. This leaves the strong possibility of a rare mutation of a key eye color gene.read more >>
