How does a child with parents with brown eyes have blue eyes?

A child’s eye color is determined by the combination of genes inherited from their parents. While the genes for brown eyes are dominant, the gene for blue eyes is recessive. This means that if a child inherits one dominant gene for brown eyes and one recessive gene for blue eyes, the dominant gene will mask the expression of the recessive gene, resulting in the child having brown eyes. However, if a child inherits two recessive genes for blue eyes, one from each parent, the child will have blue eyes.
