Are blue or brown eyes dominant?

Best Answers

Brown eyes are dominant. If you have a parent with blue eyes (bb) and a parent with brown (BB) there is a 75% chance you will have brown eyes (Bb,Bb,BB) and a 25% chance of blue eyes (bb). If one of your grandparents had blue eyes though, then your parent may carry the recessive which increases your odds to 50%. read more

So you will have brown eyes with either BB or Bb and blue eyes with bb. For gene 2, there are two possibilities, green or blue. Green is dominant over blue and so G usually represents green and b, blue. read more

Since only one dominant gene is required for brown eyes, then brown eyed parents can produce blue or brown eyed children, while two blue eyed parents should produce only blue-eyed children.
