Did You Ever Wonder?
~ About the Longhair Geneotype
There are 3 possible genotypes:
· Clear FGF5:c284G>T -/-; (those having 2 copies of the normal allele)
· Carrier FGF5:c284G>T +/-; (those having 1 copy of the normal allele and 1 copy of the long-hair mutation)
· Affected “Fluffy” FGF5:c284G>T +/+; (those having 2 copies of the long-hair mutation)
My understanding is there is typically two copies of the allele, and if both are normal, then the Weimaraner would have the traditional smooth coat. If there is one copy of the normal and one copy of the longhair mutation (as they call it), then that Weimaraner is a carrier. They look like a traditional smooth coat. Some of these carriers will have a bit of wave to their coat, and some will have a plusher coat. If both copies are the longhair mutation, then you have a longhair.
Okay – when we first learned about this we felt that if you mated a Longhair with a Carrier you would get 50% Carriers and 50% Longhairs. Whew—we soon learned that this must be an average,–because we mated a Carrier to a Longhair and we got 8 pups – 2 were Longhairs. The next year we repeated the same mating expecting only a couple of Longhairs to be born, and this time we got 8 pups—6 were Longhairs. So, we became acutely aware that it didn’t work exactly like we interpreted this chart.
Whenever we have a mixed litter, we take the DNA sample ASAP and send off the samples as quickly as possible. The other choice would be to be the home of the undocked tail. Haha Then, there would be no concern as to whether they were Longhairs or not. I do believe the world is moving toward a stand against docking, but the American Weimaraner Breed Standard is for the docked tail on the traditional Weimaraner. There is no American Standard for the Longhair per se—but worldwide the Longhair sports the full tail.
Some breeders feel that they can accurately guess which pups are Longhairs—we don’t feel all that confident. We have guessed nearly every time we had them born and then sent off for the DNA test. We are never 100% accurate. I cannot say why that is for sure. We have tried taking close up photos and looking at the hair on their ears and between their toes if the hair is smoother on the face and forehead that is an indication that you have a Longhair, too!
People are discovering the Longhair—I cannot say for sure why, but a lot of folks are equally addicted to them. Several of our clients have both, and some have converted to the Longhair. Click here to learn more about Coat Length (or the fluffy coat) test.
