![]() ![]() Dogs with furnishings can be carriers of weak furnishings or improper coat that can be passed on to their offspring. Improper coat is, therefore, recessive to furnishings and weak furnishings, meaning two copies of IC are required to inherit an improper coat. Likewise, one copy of the weak furnishings (F w) variant in the presence of one copy of improper coat (IC) produces “weak” furnishings. This means that only one copy of the RSPO2 furnishings (F) variant is required to produce furnishings. Facial furnishings is dominant to weak furnishings, which is dominant to improper coat (F > F w > IC). The three variants of the IC Locus are inherited in a hierarchical order of autosomal dominance. Genetic testing of the IC Locus for the three RSPO2 gene variants will reliably determine whether a dog has furnishings, weak furnishings, or improper coat and whether or not a dog with furnishings is a Carrier of weak furnishings or improper coat. A third variant at the IC locus has been identified and associated with “weak” furnishings that develop gradually into sparse and much less pronounced furnishings. A DNA variant in the RSPO2 gene, which functions in hair follicle development, results in the production of furnishings in multiple breeds and is found in all wire-haired dogs. ![]() The improper coat/furnishings (IC) Locus determines if a dog will have longer hair around the muzzle and eyebrows (facial furnishings) or a lack of furnishings (called improper coat in breeds for which facial furnishings are standard). Interpretation: No Furnishings, improper coat This dog will pass IC (improper coat) to 100% of its offspring and can produce puppies with improper coat if bred with a dog that carries one or two copies of the mutation for improper coat. However, the overall coat type of this dog is dependent on the combination of this dog's genotypes at the L, Cu, and IC loci. This dog does not carry the mutation for weak furnishings. This dog carries two copies of IC and will therefore have no furnishings (improper coat). Interpretation: Weak Furnishings (improper coat carrier) Therefore, this dog can produce puppies with improper coat if bred with a dog that carries one or two copies of the mutation for improper coat (IC). This dog will pass IC (improper coat) to 50% of its offspring and F w (weak furnishings) to 50% of its offspring. This dog carries one copy of the mutation for improper coat (IC) and one copy of F w and will therefore have weak furnishings. This dog will pass F w (weak furnishings) to 100% of its offspring. This dog does not carry the mutations for full furnishings or improper coat and will therefore have weak furnishings. Interpretation: Furnishings (improper coat carrier) Therefore, this dog can produce puppies with improper coat if bred with a dog that carries one copy (F/IC) or two copies (IC/IC) of the mutation for improper coat. This dog will pass IC (improper coat) to 50% of its offspring and F (furnishings, proper coat) to 50% of its offspring. This dog carries one copy of the mutation for improper coat (IC) and one copy of F and will therefore have furnishings (proper coat). Interpretation: Furnishings (weak furnishings Carrier) Therefore, this dog can produce puppies with weak furnishings if bred with a dog that carries one copy (F/F w) or two copies (F w/F w) of the mutation for weak furnishings. This dog will pass F w (weak furnishings) to 50% of its offspring and F (furnishings, proper coat) to 50% of its offspring. This dog does not carry the mutation for improper coat and will have furnishings (proper coat). ![]() This dog will pass F (furnishings, proper coat) to 100% of its offspring. This dog does not carry the Mutation for weak furnishings or improper coat and will therefore have furnishings (proper coat). The IC Locus (Improper coat/Furnishings) trait test reliably determines if a dog has one of the following genotypes at the IC locus: F/F ![]()
