The 411 - Blue Eyes

Blue eyes are relatively less common compared to other eye colours, such as brown or hazel. The prevalence of blue eyes varies across different populations and regions. In general, blue eye colour is more commonly found in individuals of European descent, particularly those with Northern European ancestry.

Eye colour is primarily determined by the amount and distribution of a pigment called melanin in the iris, which is the coloured part of the eye. Blue eyes occur when there is less melanin present in the iris, and the structure of the iris scatters light, resulting in a blue appearance.

Eye colour inheritance is a complex genetic trait influenced by multiple genes. The specific combination of genes responsible for eye colour inheritance can vary from person to person. While brown eye colour is considered dominant, and blue eye colour is considered recessive, the inheritance patterns can be more intricate.

It is possible for a child to have blue eyes even if both parents have brown eyes. This occurrence can be explained by the presence of recessive genes for blue eyes in both parents. Both parents may carry a copy of the blue eye gene, even if their own eye colour is brown. When these recessive genes are passed on to the child, and there is no dominant brown eye gene present, the child can have blue eyes.

This situation happens due to the complex interplay of genetic inheritance and the expression of different eye colour genes. It is worth noting that eye colour inheritance can be influenced by several factors, including genetic variations, genetic mutations, and chance combinations of genes during reproduction.

In summary, while blue eyes are generally less common than brown eyes, it is possible for a child to have blue eyes even if the whole family has brown eyes. This occurrence is due to the complex genetic inheritance patterns and the presence of recessive genes for blue eyes in both parents.
