Aren't they all interconnected? I mean, if a bloodline is desirable, isn't there something IN the bloodline to make it desirable?
Genes will be carried from each parent, meaning physical traits will be directly linked to the sire and dam - ugly generally throws ugly, and two nice-set horses generally won't throw a grotesque foal.
I personally don't care about bloodlines and would never buy a horse based on that. It's nice to know you can look back and find out some neat things, but other than that no.
It is over and over again that people spend thousands of dollars on horses or foals that have "good bloodlines" but turns out they don't end up in the way it was expected of them.
Yes having a sire or a dam with great conformation etc etc etc is nice and will increase your odds of having a nice horse BUT genes are genes and there are thousands of them so the end results is NEVER known. You can only guess and hope.
