However, then a different kind of consideration comes in.

The genome is incredibly complicated.

And it's not just that this picture that we have, you've got a gene for a good teeth.

It's much more complicated than that.

There are probably all kinds of genes that affect the integrity of your teeth.

And some of those genes may do other things that have nothing to do with the teeth.

Some genes are really multifunctional.

We're only beginning to catch on to this.

Or take sickle cell anemia.

It's a disease.

But some people think that the disease, the genes spread through the population because they conferred some degree of immunity to a certain kind of parasitic fly.

Now,

When we're monkeying with the genes, do we know what we're really doing?

We have the intention of curing this defect over here and it does all of this.

We even have that problem in ordinary medicine.

Before something is prescribed, your doctor has to say, now what other medications are you using?

This interacts with this, but it only interacts with this if you're also using this.

Or it'll interact with this if you're overweight, but not if you're underweight.

And it has this long list of possible side conditions.

Do you have any of these predisposing things going on in your body?
