fifty percent for brown or blue

B - Brown
b - Blue

these are the possible combinations, the mother will always pass down a blue eyed allele, and the father can give either a blue or brown, theres a fifty percent chance of each.

Bb  the Brown from dad and the first blue from mom
Bb  the brown from dad and the second blue from mom
bb  the blue from dad and the first blue from mom
bb   the blue from dad and the second blue from mom

 sorry it's so confusing to type
