Re: [RC] Genetic diseases - heidiYes, but who wants to take a chance that their SCID positive stallion will sire a SCID positive foal when crossed with their mare of probably arab, but unregistered parentage? Why would you breed a positive stallion to an untested mare? The whole point of having a genetic test is to be able to eliminate having an affected offspring. If you own the stallion, you have control over what he breeds. You can choose not to breed untested mares. The point I was making is that per those who study population genetics, one should use gene tests to steer away from those very sorts of matings, not as a means of just chopping carriers out of the gene pool. When you do the latter, you also eliminate genetic material that you can never replace.
