Eye color is a polygenic trait, meaning it is influenced by multiple genes working in concert, rather than a single gene switch. The allele for brown pigment is typically dominant over the allele for blue, but this does not create a strict hierarchy that ignores the influence of other genes.
Blue Eyes Green Child Genetics Truth: Understanding the Role of Modifier Genes
Blue eyes, contrary to popular belief, are not because they contain blue pigment. However, this scenario would require a very specific and uncommon genetic alignment that defies the typical inheritance patterns of most blue-eyed couples.
The Role of Modifier Genes To understand the theoretical possibility, one must consider modifier genes. This bump in melanin could shift the light-scattering properties of the iris from a clear blue to a green or hazel appearance.

These are genes that do not directly produce pigment but influence how much pigment is produced and distributed in the iris. Variations in this gene play a significant role in determining whether someone has blue, green, or brown eyes.
