so if each parent had a dominant gene and a recessive gene, B and b respectively, the combos would be like this:

bb, BB, bB, Bb

expressed as:

bb = blue eyes
BB = brown eyes
bB = brown eyes (brown trumps blue)
Bb = brown eyes

So the child has a 1 in 4 chance of having blue eyes, and a 3 in 4 chance of having brown eyes.
