Eye Color Inheritance
Could Eye Color be a Clue To Paternity?
Could you tell if your baby was yours just by looking into their eyes? Maybe. At least, that is what researchers are saying.A new study conducted by the University of Tromso suggests a child's eye color may reveal their paternity. The human eye, according to the study, reflects a predictable genetic pattern that demonstrates how traits are inherited. The studies, to be published in the journal Behavioral Ecology and Sociobiology, find that blue-eyed men typically find similarly colored women more attractive than their darker counterparts.
This may be due to an unconscious adaptation men have to detect paternity, related to eye color. What this means is blue-eyed men prefer mating with blue-eyed women because they will produce blue-eyed offspring... which are clearly identifiable as one's own child. A blue-eyed male who mates with a blue-eyed female and has a brown-eyed child may raise a few eyebrows.
This new study confirmed that even today, modern blue-eyed men have a distinct preference for blue-eyed women, even when all other factors are held constant (like the attractiveness of the girl).
1. If both parents are blue eyed then all children are likely to have blue eyes.
2. If both parents have darker eyes, and blue eyes run in their families, then roughly ¼ of the children will have blue eyes and the rest brown.
Typically brown eyes represent a dominate allele thus are more common than blue eyes, which represent a recessive trait. If a child is born with brown eyes and both the mother and the father have blue eyes, then one might conclude the child does not belong to the biological father.
