I personally don't think it is affecting the Olympics as much as people seem to think it is. I mean, just because someones horse is doing well does not mean it is a heart horse. (Please realise I'm not pointing any fingers here, in the grand scheme of things I know as much as everyone else, only Nef can tell us if a horse really is a heart gene or not). I agree with what elise said, there are so many hidden factors that could be affecting placings, and several people have 2 or 3 horses that are doing incredibly well - the chances of that one person getting that many heart horses for the Olympics is very unlikely, especially considering on the main page it states: "a few hundred horses with this gene have been born in the past few weeks (out of about 5,000)", which shows that there really aren't that many.
As for whether or not the heart gene should have been 'turned off' for the Olympics, I think it was right to leave it active, based on what I just said.

Aww Valbognir that's not true at all! Like Bama and other Ops have said before, the gene isn't enough to make a badly trained horse win, infact if the horse isn't well trained it just won't win. Whereas if you have a well-trained horse (like yours), and the HG you're on to a winner

. The gene only makes a very small difference, and in events like Dressage where all of the horses are so well trained and therefore have similar stats the HG can make all of the difference, and that therefore excentuates (sp?) the effect of it
