You didn't. Sorry you feel the "last post of death" syndrome.
Probably I did, but I haven't had the last questioner confirm my reply as correct.

A change of pace.
Multiple choice.
Which breed of dog is most closely related (genetically) to the wolf?
A) Russian wolfhound
B) German shepherd
C) chihuahua
D) shar-pei
E) poodle
F) Ibizan houndLar

In reply to I'm just going ahead with question # 9, posted by Larry Hoover on May 22, 2005, at 20:54:49
While all dogs are relatively closely related to the wolf, my guess is the Ibizan (f), an ancient breed. If true, has this genetic proximity been confirmed through DNA, Lar?

The Ibizan that presently exists was shown to be a re-invented breed, no more than 200 years old.
Yes, this was a major study of genetic drift in dogs.
So, f is wrong. We're down to five breeds.

Actually, the German shepherd was unrelated to all other shepherd-type dogs, and had closest affinity with boxers and mastiffs.
Down to four.

I prefer to think of it as a well-written question, rather than as a tricky one.
But then again, I knew the answer.

It would be the chihuahua, as it's a natural breed and all.

I must have clicked the nm box. Sorry, there was a message.
The chihuahua, unfortunately, was one of four breeds that failed to display unique identifying genes (all others could be identified from a blind sample, after the initial analysis was done).
The other three breeds without consistent genetic markers were the perro de Presa Canario, German shorthaired pointer, and Australian shepherd.

> > Australian shepherd.
>
> Is that the breed that is really american???Before I go on, I'd like to say that I am not a dog expert. I find the genetics fascinating (genetype), and breeds also (phenotype). It is the interplay of genotype and phenotype that fascinates.
Genotypy is the specific form of the DNA; which variant, if you will. At a specific gene, sometimes there can be dozens of versions of the DNA (called alleles) coding for a specific trait (e.g. coat or eye colour). Phenotypy is appearance. Sometimes a phenotype can be produced by different, distinctive gene combinations. Usually, though, a stable phenotype (such as a breed) is produced by a stable genotype. That occurs only through inbreeding and selection, which stabilizes the genes.
Back to the Australian Shepherd. A quick google search confirmed it.....an American "invention", and one so recent the breed has not stabilized genetically. An interesting quirk is the preference for a merle coat pattern, pictured here: http://www.dogbreedinfo.com/australianshepherd.htm
As the gene that confers the merle coat also contributes to blindness/deafness, the herding capability of the dog seems to be secondary to its appearance. It's a dog show dog.

> Kind of border collie like..The only one I had seen looked like a border collie, as well. Shorter coat, shorter muzzle. Same mesmerizing eyes.

There are three possible choices remaining for the answer to the question, which breed is most like the genetic progenator of dogs, the wolf.
Is it:
Russian wolfhound?
poodle?
shar-pei?Lar

It is down to three, from six. I have posed one correct answer among five others. Three of those five have been eliminated.
It looks good for you, dude, even if you guess.
