I've been thinking. (Yes, I know, not always a Good Thing (tm) where I'm concerned, but what the hell.)

How many people on Atlantis have the ATA gene? And I'm talking either naturally or through the gene therapy. So far, I've got:

John
Rodney
Carson
Markham

So, John and Carson are natural, and Rodney is gene therapy. (Is Markham natural or therapy?)

Where I'm going with this is here: Unless it has a pretty low rate of success, I'm assuming the gene therapy took with other people. However, canon suggests it didn't.

Okay, so three Jumpers went into the air to go after the Wraith dart. One was piloted by Markham, one was Carson, and one by some unnamed third person.

The thing I'm trying to figure out is: why was Carson piloting one of the Jumpers? Okay, he has the gene, but he's also the CMO. The non-military CMO, which means surely they wouldn't send him up in one of the Jumpers if more of the military guys had the gene. Which implies that there's not that many people on Atlantis with the gene. Or rather, it implies that there's not that many of the military on Atlantis with the gene. Hmm... maybe it just took with the scientists *grin*

So, people on Atlantis with the ATA gene? How many do you think?
