Someone PMd thus


Look at it like this:

MOM A a
DAD A a

Kid gets one gene from each parent. Two brown eyed parents can have a blue eyed child
as long as one of THEIR parents passed them the recessive gene.

In the above example, there are 4 possibilities, with one gene from each parent: AA,Aa,Aa,aa.

The AA individual will have brown eyes and NOT be able to have blue eyed children.
The Aa children will have brown eyes but be able to have blue eyes kids.
The aa (1 in 4 chance) will be blue eyed.
I agree with that, but it requires TWO people to have the recessive gene. Again, my question is if only one person has this accidental gene how can they pass it on?
