No, you can't get a Parti from one parent carrying the recessive gene. Since the gene is recessive both parents have to give it before it "shows" on a dog. You need two recessive genes to actually "see" the trait, but only one dominant gene to "see" the trait. Mom and dad each have two genes for that trait, so that's a total of 4 genes combinations that could be given. Now if mom and dad both exhibit the Parti trait they can only give the recessive gene to the offspring. People often think of recessive traits as skipping a generation, but this doesn't happen the gene is passed on, but because it's recessive it just doesn't show, until another recessive gene is placed with it.

how interesting, thanks I appreciate you taking the time to educate me.

Hi Lorraine and thank you for your support of what we are doing for the breed. I'd like to clarify the reason for our testing almost 100 Biewer TERRIERS to date and that was to prove that they were not Yorkshire TERRIERS. The standard of 4 white legs, feet, belly, chest and tip of tail is the first clue, among many, that something else was in the breed. The si gene is usually responsible for patterned coloring, the sp gene would be responsible for the black and white spotting across the back, and the sw for the predominantly white color dogs. NONE of which the Yorkie possess.
Our Geneticist, said "The chances of such independent mutations bumping into each other are astronomical. A stray chunk of chromosome from a little cross-breeding wandering into the mix is much more probable".

The reason for the name Biewer Terrier is quite simple. Biewer, the man that originated the breed and Terrier, the type of dog we are breeding, thus Biewer Terrier.

We have updated our web site and have not got all the pictures back up. We back up what we say with documented facts. We don't add our own interpretation to the findings as some people do. Any one wanting to see the information proving the Biewer TERRIER a breed of their own may email me and I will provide them with the information.

As far as the parti goes, I can't help think that they are all the sudden looking like our Biewers. A few years back there were only a hand full of parti breeders, with dogs that look nothing like the Biewer. To bad AKC doesn't require DNA on ALL breeding dogs.
I am not saying that all the Parti breeders are mixing Biewers with their Parti's, please don't misunderstand me.

Anyone wanting to work toward the betterment of the breed may contact a BTCA, Inc. representative for more facts.

wow.. these are all great posts.. thank you...
i was wondering if there are any other akc recognized dog breeds which carry the piebald gene? like maltese?

I think it's very interesting to see how each established Biewer club and group of enthusiasts has their own opinions, theories, research, goals, motivations, experiences, etc regarding this breed and to see how those things differ and compare to one another.

They are certainly fabulous little dogs so it is not hard to see why so many people are in love with them.:luvu:

Recessive pie bald genes result in parti coloring for many breeds. There are parti poodles, schaunzers, chilhuahuas, and spaniels to name a few. I have no clue if any of those breed club standard includes the parti coloring. And like YTCA...there are some who highly discourage breeding any dog which exhibits this trait.

I've never heard of a parti-colored Maltese...no clue if they exist. Maybe you can create one? :p

Wow, what a interesting thread.

they do have the white hair.. is this a pie bald gene?
this subject is probably a thread killer.. sorry:animal-pa

to the o.p. :)

This is an age old subject that tends to get very heated and is very emotional for some yorkie owners. I also asked this question when i first joined and i was like WHOA what did i just ask??? lol :eek:

I read all the posts I could on the topic and drew my own conclusion :rolleyes: Thats really all you can do!

I went back to the very first yorkshire Terrier...read about him. Read about where the breed came from in the first place, and drew my conclusion from there. I dont think many genetics are on file from the very first mixture of dogs that made up the yorkie in the first place so to me seems hard to prove what came from what and what is in the to begin with :rolleyes: It is a very interesting topic when it doesnt get out of hand....Honestly as of today there is no for sure answer. There is speculation and some tests saying where they think it came from. Like someone said earlier these things can take decades.

Not a Maltese expert, but I would think not. Any and every dog that is white or has white on them somewhere is not neccessarily the result of the pie bald gene presenting itself.

I'm sure if the dog doesn't have any white hair....the Yorkie owners will after this debate....LOL...keep smiling:D :cool:

In the early 1900's there were parti colored maltese and solid colored ones. The first maltese born and registered in the US was white with black ears.

From what I've been told, the maltese is the extreme example of a spotting pattern ... basically just one big spot! Maltese do have mottling on their skin (parti's do as well) and are often born with lemon coloring on their ears and bodies.

Just trying to understand...
 

Recessive genes, mutations, and how variations work I understand so I don't need explanation on these.
From what I've read genetic testing has been done to prove that Biewers are there own breed of dog. Right?
And parti yorkies, and this is just a theory, could have resulted from a genetic mutation that resulted in the recessive lighter color gene. Or was the recessive gene always there? Did breeders just breed against this coloration favoring the dominant color we've all come to know?

I know that Cocker spaniels show parti coloreds.
