[Still Thinking]

Your parents both carry the recessive gene for blondness. The gene is called recessive because when a given individual has both a recessive gene and the corresponding dominant gene (in this case, for dark hair), the dominant gent wins out. Even so, the individual is a "carrier" for the recessive trait in that he can contribute the recessive gene to offspring. Your sisters got a blond copy from both your father and your mother, while you and your brother got two darks or a dark and a blond gene. You and your brother could have blond children if you are blond "carriers", but if your sisters marry blond men, they will by definition have blond children.

So ... do the 'creationists' buy into to the presence of these genes and the effects differing genetics of 'father and mother' can have?

Or is that part of the dreaded 'evolutionist' agenda?
