![]() Although individuals with darker skin tones generally have a higher concentration of melanin in their eyes, there can still be variations in eye colour within any racial or ethnic group. Eye colour is primarily determined by the amount and distribution of melanin in the iris, which is influenced by genetic factors. ![]() While it is relatively rare, it is possible for Black individuals to have different eye colours, including blue, green, or hazel. Therefore, while there may be some general patterns in eye colour distribution across different racial or ethnic groups, it is not a definitive determinant and individual variation is significant. Similarly, in populations with a higher prevalence of blue or green eyes, individuals can still have brown or hazel eyes. For example, in populations with a higher prevalence of brown eyes, individuals can still have blue, green, or hazel eyes. While some eye colours are more commonly associated with certain racial or ethnic groups, it is important to note that eye colour can vary within those groups as well. The genetics behind eye colour is not fully understood, but it is believed to involve the interaction of multiple genes. The combination and concentration of these pigments determine the colour of an individual’s eyes. Melanin exists in two forms: eumelanin (brown to black pigment) and pheomelanin (yellow to red pigment). It is primarily determined by the amount and distribution of the pigment called melanin in the iris, which is the coloured part of the eye. While certain eye colours may be more prevalent in certain ethnic groups due to genetic variations, eye colour is a complex trait influenced by multiple genetic factors. Eye colour is not solely determined by race.
