RE: [RC] Old arab blood - heidi

Barb, the main key is whether or not the other horses in the pedigree are of like type.  A horse many generations back that is the only one of his/her type is not apt to lend much to the current horse standing in front of you.  So, when breeding programs change directions, the resemblance is usually drowned out in the predominant type in the pedigree.
 
That said, one still sees throwbacks, often many generations back.
 
On the other hand, take a horse like Mesaoud.  We do not "intentionally" select for Mesaoud specifically in pedigrees, but do value many of his descendants.  We have selected our horses based upon their conformation, metabolic ability and trainability, and found that that led us to a somewhat narrow range of bloodlines.  In looking back and in analyzing pedigrees of our herd, most of our horses run anywhere from 12% to over 19% Mesaoud--and yet in only one of our horses does Mesaoud even appear in a 5-generation pedigree.  Do we see traits of Mesaoud in our herd?  You betcha.

I have a question for the people who study these blood lines and are breeders.

Can a cross bred horse of today-  with Crabbet blood (thru RAFTAN) 5 generations back- show the characteristics of that line , even though the blood is diluted through one-4 generations?

I know genetics are a tricky thing sometimes- so I guess my question is:

How many generations back is it, before a horse can't be a "throw back" to certain (especially visual
conformational traits)... 3rd, 4th - 5th generation..

Thanks,
Barb
