What Percentage of the Population Has Brown Eyes?
Over 55 percent of the general population has brown eyes. Brown eyes are the most common eye color. Brown eye color is created when melanin is present in the eye.
Eye color depends on the amount of melanin in the eye and how the color is distributed throughout the iris. The lighter one's eye color, the less melanin is present. Eye color percentages depend on the populations that are being studied. Asian and African populations are more likely to have brown eyes compared to European populations. The genetics of eye color is complex as well. Eye color cannot be determined based on the eye color of relatives. A person born to two blue-eyed parents may have brown eyes.
