So the host mare or the egg donor mare doesn't have any influence?  I still think that upbringing / inviroment would have to play some kind of role in how one turns out.

Mitrochondrial DNA is passed from the female to ALL of her offspring. Since AQHA does prove parentage on the female side as well the mitochondrial DNA is tested also.  With genes, think of a BINGO game.  You draw numbers out that fit into different catagories.  Someone wins and you put all the numbers (genes) back in the bowl and start all over.  The next game will not have the same numbers called, making each individual different but you still have the same gene pool. That is why clones do not look exactly the same or have the same abilities  

I was was just watching a thing on TV about tracking criminals’ DNA through these genealogical sites. The testing is very precise.

There are people (myself included) that think the Mitochondria DNA contributed by the tail female family has a lot of influence. Thoroughbred breeders put a lot of effort into identifying and incorporating the best female families in their programs. The x Factor heart follows the female family. There are other sex linked traits that haven't been identified that may come in through the MtDNA.

That’s all I thought of off the top of my head. There’s way more than that if you add Gem Twist, the 6 polo ponies and all the bucking horses. Plus a lot of people don’t want the public to know when they clone something so it’s kept quiet.
