First cyborgs, now clones.
At the moment, the biggest roadblocks are institutional. Thoroughbred racing will only register foals that are bred with natural mating, so cloned animals can’t compete in any of the major races. (Even artificial insemination is off-limits.) But Russell and others are hoping a steady supply of well-bred horses will change their minds, and there’s reason to believe they’re right. Just last month, the Fédération Equestre Internationale opened up international competition to clones and their descendants, which means Russell’s brood is now eligible to compete in the Olympics.
