Color Blind

Q:
My dad is colorblind. He can only see colors if there is only one main color. What I want to know is why my siblings and I are not color blind as well?
Thanks!

A:
I believe that certain types of colorblindness are due to single-gene
mutations. If the mutation happens to be recessive, then if you get a
normal gene from your mother, the defective one from your father wont
be expressed. If its dominant, then your father would probably also
have a copy of the normal gene, and each kid has a 50% chance of
getting it. If its sex-linked, then the odds change further. So its
not shocking that you and your siblings dont have the trait. Some real
geneticist (were just physicists here) should be able to identify your
fathers color blindness and tell you what the odds are for male and
female children to inherit it.
