Quote:
"chimera"
The key is the mosaic pattern to the miss marking

instead of the dog being
BBEE = black
or
BBee = yellow
as a shimera it is
BBEE/BBee

Answer 1

I wonder if a dog, like a human and other species can be a "chimera"...having 2 sets of DNA in the same body. In people they have seen similar things like the dog. A child that had half girl genitals and half boy genitals. Half caucausian skin, and half african-american skin. Must be possible.

Answer 2

This is amazing. As I'm getting started showing Labs this is of utmost interest to me. I've seen something like this once before, and both parents were purebred there as well. The only explanation I can come up with is that around 1662 when the first Labradors were "discovered" they were still being interbred with other Retrievers.

The 3rd Earl of Malmsbury in a letter written to the 6th Duke of Buccleuch said, "We always call mine Labrador dogs and I have kept the breed as pure as I could from the first I had -- the real breed may be known by their having a close coat which turns water off like oil, and, about all, a tail like an otter." However, all breeders did not always "keep the breed pure". Many breeders, realizing the excellent qualities, crossed Labradors with other retrievers. Still, if a Labrador is crossed with some other strain, the Labrador type nearly always predominated and their descendants were most always called Labradors. --- The Origin and Purpose of the Labrador Retriever by Dr. B.W. Ziessow

Perhaps sire and dam have something in their pedigree that caused this to happen. What I don't understand is that all color combinations lead to a solid color, not to a combination of colors. Labradors carry many color genes, but the essential ones are the brown series (B/b) and the extension series (E/e).
Black dogs must carry at least one B and one E
Chocolate dogs must carry bb and at least one E.
Yellow dogs can carry BB, Bb or bb but must all be ee.
Blacks can be thus BBEE BbEE BBEe. (ie all four types).
Browns are either bbEE or bbEe (ie two types).
Yellows (black-nosed) are BBee or Bbee.
Yellows (brown-nosed) are all bbee.
So if you can figure that out basically you know that whatever combination you have, you will still end up with a solid color, not a parti-color. Crazy huh?

Answer 3

I have a Flat Coated Retriver, possible lab or lab mix.
My brothers friend has two Great Pryneress or something and the dog looks just like his expect your dog has black.
I would say the parents may be full blood, but most of it's background, there was some mixing.
Possible Pryneress and lab. One mess up like that and the dogs genes are messed up and everynow and then there is a pup that takes coloring of it's ancertors.
Hoped this helped.
GOOD LUCK!

Answer 4

Cute.

That is called a Parti-color. It is a recessive gene, so both parents are carriers. If you mate the two parents again, an average of 1 in 4 pups will be particolored.

Cute and rare, because it is a "nonconforming" color according to the AKC. You can probably register the pup with the AKC but will be required to spay/neuter.

Answer 5

Some times genes mutate. All breeds of dogs orignated from wolves. Through years of selective breeding we have made these breeds, from tiny chiuahuahs to huge Great Danes. Often the mutated genes are undesirable traits and the animal will not be show quality.

Answer 6

There is no way that dog is a purebred Lab. No way!~

It is a really beautiful dog tho. I would say several generattions back, there was some other breeds mixed in and the recessive genes were carried thru the generations. This is a throwback to the other breeds. I would be proud to own this pup,but I just cannot believe it is purebred.

Answer 7

in the journey that your mom and her sister have been same twins and so have been your father and his brother than you would be an identical genetically as siblings. That being suggested you're nonetheless extra heavily like siblings genetically than you're like "typical" first cousins genetically. you're additionally extra genetically comparable on your cousins than you're on your mothers and fathers!! i don't think of there's a term for what you adult men are, yet you would be extra valuable donors for one better than any of your mothers and fathers.

Answer 8

Remember!!! there were only Two (2) of the dog kind (jackal, fox, wolf, dingo, dog, and so on) on the ark. So, you can expect-the unexpected. Like humans, there is only one race: HUMAN. There is no explanation necessary. Now if the same two Labs produced a duck-we would need an answer.

Answer 9

Photochopping? I notice that the markings have changed somewhat from puppyhood to adulthood in certain spots. Black hair doesn't turn blonde.

If the photos are legit, however.....that's not a total genetic rarity. It's not extremely common, but it sometimes happens.

Answer 10

I've read about "Chimeras" occuring in humans,but never thought of it in dogs.I suppose it could happen in any species.It's a beautiful dog,though.Is it yours?
