What's more fun than looking at pictures of DNA and celebrities? Check out Dolly, dimples and dominant and recessive traits in this fun gallery charting how genetics play out in humans (and a few animals).

How can children from the same parents look so different? I mean, why don't all kids from the same parents look exactly alike, since the parents just have one set of chromosomes each and they don't change?

Given the choice, would you rather have been born with a different eye color, hair color or skin tone? Of course, you didn't have these options, but could you have them for your own children?

Ever since I took biology in high school I have wondered -- why do humans (and plants and animals) have two of every gene, and why is one "dominant" and the other "recessive"? How does my body know which one is dominant? How does it pick between the

The physical you is a result of your DNA, and your DNA is part of the human gene pool. Find out what the "gene pool" really is and what happens when it shrinks.
