Are brown eyes a recessive or dominant trait?
The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
Is brown a dominant trait?
The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive. Given this information, you can determine what eye colors are dominant in the parents.
What is the most dominant eye Colour?
Brown
Brown is the most common eye color worldwide by a large majority. As many as 16 genes influence eye color by determining the amount of melanin inside the specialized cells of the iris. Melanin is the pigment responsible for eye color. In this article, we explain what eye color is and what causes it.

Are brown eyes dominant over Hazel?
Are brown eyes dominant over any other?
Eye color was traditionally described as a single gene trait, with brown eyes being dominant over blue eyes. Today, scientists have discovered that at least eight genes influence the final color of eyes.
Are brown eyes really more dominate?
The authors discovered that males with brown eyes were considered more dominant than males with blue eyes, but when they altered their pictures to turn brown eyes into blue, the effect persisted. Thus, it is not the color itself that creates the impression of dominance, but rather other factors correlated with the brown-eyed phenotype.
Are brown eyes more dominant then blue?
Men with brown eyes were rated consistently as more dominant than blue-eyed men. No such effect of eye-colour was found for the photos of women. Eye colour also bore no association to the attractiveness ratings. Next the researchers used Photoshop to give the brown-eyed men blue eyes and the blue-eyed men brown eyes.
