In Our Genes

For those of us with blue eyes, it all goes back to a single mutation, and one that must have been genetically advantageous. Moreover, there probably weren't any of us prior to about 10,000 years ago. Go figure.

And obesity, well, that's probably in your genes as well. As one who comes from two parents who are heavier, I for one have to be relatively vigilant about getting my exercise and not eating everything that I want. I always wonder at those friends who own their own deep fryer and never seem to gain an ounce.

And yet, as much as it may seem so, our genes are not inalterable, static things. They can be changed, and sometimes that can be used to our advantage.

  • Blue eyes. Since they are recessive, it takes two people with the gene to make a kid with blue eyes. If you start with one changed gene,that would be pretty tough at first. There were a lot of people with the recessive gene around before you got actually blue eyed people.
