I would like to respectfully reply to Arthur.  Going to the end of the post a
rhetorical question was asked ( i erased the message so pardon my quote) about
where someone would go to buy a Fjord.  I would also like to address the prior
sentence.

First, I have just bought a Fjord filly and spent more money on it, training and
transportation than I have on any other horse.  Why did I buy it where I did?  I
researched the pedigree and asked dumb questions about what the pr and numbers
were and listened to the people on the list and when one came up with BDF 
Malcolm
Locke on one side and a bunch of other  names on the other with those funny
numbers and I talked to the owner, I jumped at the opportunity because as a
novice, it was exactly what I was looking for and I trusted the quality that the
BDF stands for and the ratings that had been awarded ancestors ( I also fell in
love with the picture).  I bought her even though I was not quite ready.  My
point is, people who are willing to pay that much for a horse will do the
research and seek out quality.  In my humble and not terribly well informed
opinion, I think there is room for two ideas, one is a registry, which clearly
establishes the pedigree and history and the other is an evaluation which
establishes the quality of breeding stock against a somewhat changeable and
arbitrary standard.  The two need not be mutually exclusive.

In the hyperbole of the argument a statement was made that there was not a 
chance
in a million of a stud who had been evaluated to pass on a genetic defect.  
Here,
as a pathologist teaching molecular genetics and diseases at a University I will
have to respectfully disagree with the author.  It is very well documented that
humans and animals all carry potentialy deletorius and fatal genes and can pass
them on to their offspring without having the trait appear  in either the dam or
the sire or in several generations back.  They may be recessive or may require
another gene for them to be expressed.  It is also possible to have a point or
spontaneous mutation that arises without prior appearance in the line.  While it
is true that ruthless culling can reduce the incidence dramatically of dominant
traits in a line ( usually quite visible and frequently more cosmetic than life
threatening), there are far more recessive and /or linked traits which are not
touched by what is called phenotypic culling.  Therefore, there is NO guarantee
that even with the most ruthless of standards, a stallion will not pass on a
recessive trait.  It depends on the genes inherited from the other side whether
the trait will be expressed in a foal.  Likewise, excessive culling for cosmetic
faults without knowing linkages can lead to loss of favorable genes.  We would 
be
in a mess if the genes for resistance to a particular disease were linked to a
slight overbite.  Most traits and diseases are multifacotal - one gene does not
make one defect.  A case in point is the persistance of thalassemias and sickle
cell anemias - both potentially fatal diseases in the populations around the
mediterranean and Africa.  It has been proposed that the reason they are still
there in such high frequency and have not been deleted is that those humans who
carry the gene, but do not display the disease, are resistant to malaria,
allowing them to survive in an environment where "normal" individuals would
perish.  When we cull without knowing linkages on an already small genetic pool,
there is a very real chance that we diminish the diversity of the gene pool.  As
a person who should have had braces as a kid and  the daughter of a man who had
one undescended testicle I am glad such standards were not applied to humans.  
My
children had beautiful teeth and my sons testicles were fine.  He died as a
result of the effects of schizophrenia, a genetically linked disease which
neither  his parents, grandparents or great grandparents had any evidence of.

Sorry for the lecture but I think there is room for both views..
