ChromaGene™ Coat Color Chart B

Coat Color in Poodles

DNA research has identified the genotype associated with the brown (b allele) and cream-white-red-apricot (e allele) coloring.

What does this mean to breeders of Poodles?

VetGen has discovered that Poodles who are brown have the 'bb' genotype and Poodles who are cream, white, apricot or red have the 'ee' genotype.

The DNA Test for coat color in Poodles will allow breeders to test dogs who are NOT brown, to identify whether the b allele is present, as well as to test those dogs who are NOT cream, white, apricot or red, to identify whether the e allele is present.

The DNA test for b and e allows breeders the choice of producing dogs with brown coat color, as well as the opportunity of breeding away from the cream, white, apricot or red coat color.

The ChromaGene™ test will determine which one of the genotypes listed below your Poodle is:

If your dog is black the possible genotypes are: BBEE, BBEe, BbEE, BbEe.
If your dog is brown, the possible genotypes are: bbEE, bbEe.
If your dog is cream, white, apricot or red with a black nose, possible genotypes are: BBee, Bbee.
If your dog is cream, white, apricot or red with a brown nose, your dog's genotype is bbee.

ChromaGene™ testing is valuable for determining if a breeding pair is carrying e, b or both and would therefore be capable of producing the brown or cream-white-red-apricot coat color.

Once your dog has been tested and you know its genotype, use this table for breeding strategies and breeding stock selection. The outer ring shows the visible coat color with the small upper right circle showing the nose color(black or Brown). The inner rings show the hidden color genes carried by the dog. Entries in the table show the probabilities of producing various coat color within a litter.

For example, if your results show that your dogs genotype is a Type Bbee, your dog is cream, white, apricot or red and has a black nose, the dog is carrying the hidden genes for black and brown. If you were to mate this dog with a dog of the genotype bbEE, on the average, half of the Litter would would be black and the other half of the litter would be brown.
These probabilities represent expectations averaged over the long run and are subject to the law of probabilities.

Note that any breeding which produces both Brown or Cream, White, Apricot or Red, has the potential to produce brown nosed cream, white, apricot or red. If the breeding does not have the potential to produce blacks, only cream, white, apricot, red and brown, all cream, white, apricot and red will have brown noses.
