The Hr Locus (Hairless) trait test reliably determines if a dog has one of the following genotypes at the Hr locus:
Interpretation: Embryonic lethal
This dog carries one copy of the dominant Hr allele and one copy of the recessive hr allele which produces hairlessness. This dog will pass on the Hr allele to 50% of its offspring and the hr allele to 50% of its offspring.
This dog carries two copies of the recessive hr allele which results in a coated dog. This dog will pass on the hr allele to 100% of its offspring.
Interpretation: Coated, Powderpuff
