Brown eyes are the most common eye color, stemming from a complex interplay of genetic factors. This ubiquitous trait raises intriguing questions about its global prevalence, often sparking curiosity about the underlying genetic mechanisms. Dr. Robert Green, a geneticist at the Genomic Institute, explains that eye color is determined by multiple genes contributing to the amount and type of pigment in the iris. Dominance of certain alleles results in brown pigmentation, which is prevalent due to its genetic advantage in various environments, offering protection against UV radiation. The widespread occurrence of brown eyes, from Africa to the Americas, underscores its evolutionary success. It highlights the importance of understanding hereditary patterns in fostering knowledge about human diversity and adaptation. As research progresses, scientists gather crucial insights into genetic variations that influence not just physical traits but also cultural dynamics across populations.
