L-Locus (length)

£30.00

The L-Locus is a region of your dog's DNA which controls whether they will have long hair like a Golden Retriever, or short hair like a Labrador Retriever. This is also known as fluffy in some breeds.

Long hair is caused by a mutation in the FGF5 gene. Long hair is recessive meaning a dog must inherit two copies of the mutation for long hair to be expressed. This test is for the L1 variant which is common across almost all dog breeds, there are also the L2 and L4 variants which are specific to some other breeds which we don't currently test.

Results:

Your results will be reported as one combination of the L-locus alleles with the following interpretations.

 Sh/Sh - short haired
Sh/L - short haired carrying long
L/L - long haired
