Sire or dame , which is most important ?

This is more of a shopping than breeding question but it does pertain to breeding .
Traits and bloodlines. I know some cultures tracked mares while other stallions.
In breeding does one parent determine traits more than the other ?
IE in a breed cross, will a colt be a mix or be more like sire or more like dame ?

I think that the personality will be a lot like the dam because they essentially raise the horse. However, some lines are known for "stamping" offspring.
For example my horse is out of a Come Back II mare (known to be a hot line and the mare is very hot, and big/tall) but by Rotspon (known to be totally cool headed and small and the R line stamps). He will sometimes get fizzy but for the most part is totally cool about everything just like his dad. He also looks almost exactly like his dad. He wears a 76/78 which is an R line thing (the size) where as his mum is an 82. But he has I think a better ability to "lock on" to something from the dam line, he has a lot of focus. And from the dam he is a very very good herd leader, very bold and brave.
His half sister, by a less stamped line is a spitting image of her mother in temperament and looks, but the addition of the sire line improved on the dressage ability.

So, it depends but I think that the dam line is more important than the sire line, in general. A good mare will produce a good horse when bred to a good stallion regardless while a so so mare will produce decent horses only when paired with a stallion who really stamps his offspring in a good way.

Depends, some stallions "stamp" their babies to have more of their own traits while other stallions don't contribute a lot and their foals look more like the dams.

Most experienced breeders, myself included, know that, in general, the dam has more influence than the sire. Although the overall ramifications are not yet known, the fact that the mtDNA comes from the dam is at least part of the reason.

However, that doesn't account for prepotence, which, again, is still a bit of an unknown. Some bloodlines are far more prepotent than others, so sires can exert more influence if their lines are more dominant.

My advice is to study the prepotency of the bloodlines with the understanding that the dam's influence tends to be somewhat higher than the sire's...

Ok makes sense, so playing law of averages, an Arab mare TB sire, would more likely produce a more Arab like offspring than a TB mare X Arab stud.

Probably, but again much depends upon prepotency. TB's are of primarily Arab origin, so on paper the cross makes sense, but honestly I wouldn't recommend it in your case. If memory serves me correctly, your discipline is endurance. Remember that TB's have been bred to be overspecialized. Ask yourself if you want to use a cross where one of the breeds has a current history of fragile bones, joints, and hooves. If you only do flat work on dirt that cross may be OK, and it is certainly OK for dressage type events, but I wouldn't recommend it if you plan to do any endurance in moderate or rugged terrain. That doesn't mean no TB/Arab cross can do rugged endurance, but it is not a direction I would go in myself...the risk of injury and breakdown is just too high. I think half Arabs are the best endurance/trail horses there are in more rugged terrain, but I prefer to cross the Arabs with Appys or Quarterhorses (with the proper fast/slow twitch muscle composition), resulting in endurance with power, and sound bones, joints, and hooves. Just my opinion, of course...

I concur, full would be best , hard to find a big one though, and TB and TB crosses are coming out of the woodwork in my area. Pretty much every where.

Yeah, you are in TB country. One of my favorite drives, although it is northwest of you quite a bit, is from Charlottesville to Culpepper...some beautiful horse farms there. It would take a powerball lottery to buy one, though...

Ive always wondered where the heck those people work. No industry anywhere, but giant beautiful houses and barns.

I believe the mare is the most important due to the fact that most foals will adapt to their dam's attitude since they're with them every day. The sire does have contributions but you should look the mare to see if she should even be bred in the first place. With some mares, you'll get lucky the stallion adds his good traits verses some bad mares.
