No one knows it well. There are some basic rules to follow but genetics is an extraordinarily difficult thing to predict. Now you will get few admiting this but its the truth.

There is not one gene in the horse genome that anyone has related to racing success. And the mapping of the thoroughbred genome is very close to complete.
