VetGen has introduced a new DNA test for Dalmatian Coat Color. DNA testing has identified the genotype associated with the liver spot (b allele), and orange or lemon spot (e allele) coloring.

What does this mean to Dalmatian breeders?

VetGen has discovered that Dalmatians with liver spots have the 'bb' genotype and Dalmatians with orange or lemon spots have the 'ee' genotype.
The DNA Test for coat color in Dalmatians will allow breeders to test dogs who do NOT have liver spots, to identify whether the 'b' allele is present, as well as to test those dogs who do NOT have orange or lemon spots, to identify whether the 'e' allele is present. 
The DNA test for b and e allows breeders the choice of producing dogs with liver, orange or lemon spots, or the opportunity of breeding away from these colors.

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

If your dog has black spots the possible genotypes are: BBEE, BBEe, BbEE, BbEe.

If your dog has liver spots, the possible genotypes are: bbEE, bbEe.

If your dog has orange or lemon spots with a black nose Possible genotypes are: BBee, Bbee.

If your dog has orange or lemon spots with a liver nose Your dog is genotypes bbee.

The value of the ChromaGene™ Test is, that it determines if a breeding pair is carrying e or b, or both and would therefore be capable of producing the liver, orange or lemon coat color spots.

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 liver). The inner rings show the hidden color genes carried by the dog. Entries in the table show the probabilities of producing various coat color spots within a litter.
For example, if your results show that your dogs genotype is a Type Bbee, your dog has orange or lemon spots and a black nose, the dog is carrying the hidden genes for black and liver.  If you were to mate this dog with a dog of the genotype bbEe, on the average, half of the Litter would have black spots and the other half of the litter would have liver spots.
These probabilities represent expectations averaged over the long run and are subject to the law of probabilities.
