Equine Genome Project Gives Modern Breeders a Big Fat FAIL

What you may ask has this to do with purebred dogs.

 

actually a lot now we live in the age of dead end kennels.

 

less sires available to maintain diversity just for starters it seems.  Without even dipping into the subject of shrinking female lines available

That foal looked much younger that what they estimated. It looked pretty much newborn to me.  Not that it really matters after all this time.

I'd guess the problem is worse with dogs cause one mating can produce several pups

what led you to that conclusion?  multiple puppies gives multiple genetic combinations, ask any geneticist, you actually need 100 from the same parents to get the best sample of all the possible combinations and that's a huge diversity to select from, I was taught by Glen Roberts  a world recognised geneticist   (you can check publications, yourself, but that takes time and many hours researching, months actually to find the best relevant data for what you wish to learn.)...  the minimum number of progeny of  a pair needs at least 36 progeny to give a vindow to a fair sample of what they actually carry... Few horses produce even ten, twenty max...so selection is far far slower than can be achieved with dogs.

 

but today few even bother to learn, why should they. to be "ethical" today even one litter is deemed sufficient. even just one pup and accept that and hope it is not hiding genes you would have a fit if you knew they were there.

so so many extort to never make two mating's of the same parents, that's puppy farming today.   Not giving yourself and the breed, the best chance to select the best possible combination from the parents. Let alone find what todays dna tests dont even have markers for yet and probobly wont for decades, there are thousands of them just waiting to say "HI".

 

best breeding practice has been eliminated in the race to be "ethical" with no understanding of the ramifications of artificially shrinking the possible gene pool that could have been available for selection.

 

what you can actually see, when you look at a puppy is a fraction of what is actually carried and not yet expressed.... its what you cant see is the big question..

I said guess, not conclude

Taking a wild guess is often a good way to get someone to expand on a subject.
