Sometimes, genetic make-ups do not show up as traits. Let us assume Jane has beautiful brown eyes. Her dad has beautiful blue eyes (pure-bred blue eyes, to say, he has only blue eye genes), while her mom has beautiful brown eyes (pure-bred brown eyes, to say, she has only brown eye genes). Then Jane must be a half brown eye and a half-blue eye, but she has only brown eyes. Why and how this could happen?
