Now, for the first time, Doberman Pinscher breeders and owners can test a black Doberman to determine whether the dog is carrying the gene that causes the "red" color. This information will allow breeders to decide if they would like to produce "red" Doberman puppies in their next litter.

The ChromaGene™ test will determine whether your Doberman is either of these two genotypes:

BB: Your black dog will not produce red offspring.

Bb: Your black dog is carrying the red gene (b) and is capable of passing this gene on to its progeny. Some red progeny may occur if you bred two dogs who are black, but are both carrying the red gene (Bb).  Your black (Bb) dog  will almost certainly produce red offspring when mated to a red (bb) Doberman.

The value of the ChromaGene™ Test is, that it determines if a black breeding pair is carrying b and therefore capable of producing the red (brown in some countries) coat color.

Statistical Outcomes of Mating Pairs:
 

Breeding Pair Combinations	BB	Bb	bb
BB	100% BB	50% BB 50%Bb	100% Bb
Bb	50% BB 50%Bb	25% BB 50% Bb 25% bb	50% Bb 50% bb
bb	100% Bb	50% Bb 50% bb	100% bb

Alternate way of displaying the information contained in the table above

Breeding Pair   =   Progeny  

BB x BB = 100% BB (black)

BB x Bb = 50% BB (black), 50% Bb (carrying red)

BB x bb = 100% Bb (carrying red)

Bb x Bb = 25% BB (black), 50% Bb (carrying red), 25% bb (red)

Bb x bb = 50% Bb (carrying red), 50% bb (red)

bb x bb = 100% bb (red)

VetGen has not discovered the gene responsible for dilution, a mutation at a different genetic locus influencing the coloring of Dobermans. Please re-visit our web site occasionally for information pertaining to any new discoveries.
