Dominant gene is Brown or B. Recessive gene is blue or b.
So if two BB mate automatic brown eyes.
If two bb mate automatic blue eyes.
If a BB and a bb mate either brown, green or hazel. No way to do blue.
If a BB and a Bb mate again no blue. 25% chance of a BB brown
If two Bb mate 25% chance of BB or bb. 50% chance of brown green or hazel.

Draw a box with 4 squares. Dad on top, mom beside. Then you get this
B b
B BB Bb
b Bb bb

Was that what you were thinking?
