Newfoundlands colour variants

In the Newfoundlander dogs have black, brown or grey coat colour. Locus B is responsible for black or brown coat color in Newfoundland dogs. Genotype b/b induces brown coat color; genotypes B/b and B/B cause black coat color. A dog with B/b genotype is also a carrier of brown color.

The grey coat colour is a suitable example of mutual effect of the individual alleles. The lighter shades of black are a result of the effect of alleles in D-locus („Dilution") and the phenotype in a dog with dd-genotype is expressed with grey coat colour.

Tests for all loci mentioned are performed by Genomia laboratory -  continue to place an order and for detailed information

• locus B
• locus D

The tests are performed on samples of blood or buccal swabs.
