The ancestry of the modern thoroughbred traces back to three main sires. The Darley Arabian, the Godolphin Arabian, and the Byerly Turk.
Yes. They can be three years old only.
No. Only three year old thoroughbreds can enter the derby, so they can only enter once.
Yes. Full siblings would have the same parents. Half siblings would have the same mother (technically if they had the same sire but, at least in Thoroughbreds, the term is generally used for the mare's offspring only because stallions produce so many foals).
Thoroughbreds ONLY
That's the only kind of stallions there are. A stallion is an uncastrated male horse. The other male horses are geldings which are castrated males. That only leaves mares.
Only 3 year old Thoroughbreds are allowed to run in the Kentucky Derby. No other age is allowed.
Thoroughbreds are purebreds with a closed studbook, therefore only two Thoroughbreds can create a Thoroughbred foal. No other breeds are allowed or used.
No paints have won the Kentucky Derby. It is only for purebred Thoroughbreds and that breed cannot be paints. Paint is a breed, pinto is a color, and Thoroughbreds can only be solid colors, no pinto.
No it doesn't, Well only when they Pee.
Zenyatta and all of her foals (Cozmic One included) and their sires (fathers), are all Thoroughbreds. Out-crossings are not allowed in the Jockey Club only purebred Thoroughbreds.
