The L Locus (Long Hair/Fluffy) Lh1 trait test evaluates the L Locus for the common Lh1 Mutation that has been associated with long hair in many breeds including the Corgi, Labrador Retriever, and Chesapeake Bay Retriever, among others. Long hair is also referred to as fluffy coat in some breeds. This test will reliably determine if a dog has one of the following genotypes at the L locus:
This dog carries two copies of Sh which results in short hair. This dog will pass on Sh to 100% of its offspring.
Interpretation: Shorthaired (does not carry long hair)
This dog carries one copy of the Sh and one copy of the Lh1 mutation which results in short hair. This dog will pass one copy of Sh to 50% of its offspring and one copy of Lh1 to 50% of its offspring. This dog can produce Lh/Lh offspring if bred to a dog that is also a Carrier of an Lh mutation (Sh/Lh or Lh/Lh).
Interpretation: Shorthaired (carries one copy of long hair)
This dog carries two copies of Lh1 which results in long hair. This dog will pass one copy of Lh1 to 100% of its offspring.
Interpretation: Longhaired (carries two copies of long hair)
