SOME CAVALIER IN-BRED CO-EFFICIENTS
If the Researchers cannot be being Believed about the Cavalier Breeding Guidelines they are giving to Cavalier Breeders ,then who can be Believed.
It is such a Foolish claim to be made ,OH WELL, The Breeding Recommendations have never been Proven to Work .
WHO SAYS.
The same few Cavalier Breeders who probably have never given those Breeding Recommendations the Chance to see if they could be Successful or not.
Why do they seem to think that they should be the Voice of All Cavalier Breeders, do they not realize the Harm they are Inflicting on the Future of our Cavaliers , that is ,if the Cavaliers do have a Future , which is a Big Question at the Moment.

SOME CAVALIER IN-BRED CO-EFFICIENTS
Because I have been collecting the Ages of Long Lived Cavaliers for many years now and had noticed that a number of them had High COI's but had lived to a good age ,I've often wondered about this.
If I could Post this Reply that I have just received ,it might be of a wee bit of Interest.
"The COI is not inherently good or bad .
It is a Probability that due to Common Ancestry of an Individual's Sire and Dam that the Individual will have both Gene Variants from an Identical Ancestral Source at any Gene.
So, Progeny of a Full Sib Mating (where the Parents of the FSIBS are unrelated) is 0.25,i.e.there is a 25% chance that at any Gene (given a few Technical Assunptions) the 2 Coppies Inherited are Idenical .
This may be due to Selection for a Certain Trait ,or due to Small Population Size etc.
It is Important as a Measure of Risk ,since all Individuals Carry Defective Genes (MUTATIONS).
When Paired with a Fully Functional Copy ,they do not Represent a Problem ,but when COPIES are the Defective Version then Disease can Arise.
So the COI Represents a Risk of this of this happening , but does'nt make any Assessment of which Gene Pairs may have Identical Copies and Effects of Defective Copies.
Therefore ,it is quite Possible for Highly In-Bred Dogs to Live a Long Time. "
I hope I have understood this right, that it means that even although a Cavalier has a High COI ,lived to a Good Age, that it can be being said that Such and Such a Cavalier ,with a High COI lived to 15 or 16 years of age , so having a High COI makes no Difference , it depends on how Genes have Paired up for that particular Cavalier.
Hope this has made sense to you .
That Cavaliers with a High COI ,could still be at Risk.
