Hello, I'm an expert in genetics and human biology. When it comes to eye color, it's a trait that is influenced by multiple genes, with the most significant being the OCA2 and HERC2 genes. These genes are responsible for the production of melanin, the pigment that gives color to our eyes, hair, and skin.

In terms of dominance, brown is considered the most dominant eye color genetically. This is because brown eyes are the result of the production of melanin, and the genes for melanin production are dominant over those for lower melanin production, which results in blue or green eyes. However, the inheritance of eye color is not a simple dominant-recessive pattern; it's more complex due to the involvement of multiple genes and the environment.

So, to answer your question, brown is the more dominant eye color in the genetic sense. However, the actual distribution of eye colors in a population can be influenced by many factors, including historical migrations, genetic drift, and interbreeding.

As you'll see, this is usually when a trait is on the X chromosome. Let's say that a child has a mom with brown eyes and dad with blue eyes. Since brown eyes are dominant, the mom can have either one brown (B) and one blue (b) version of an eye color gene or she can have two browns.read more >>
