How do I Know if my Whippet Carries the Mutation for Myostatin Deficiency?

We offer breeders a fast, affordable and reliable DNA test for identifying the varying genotypes for Myostatin Deficiency in Whippets. Breeders can use DNA testing as a tool to better manage their pairings and make more informed selection decisions for future generations.

Commonly referred to as the “Bully gene” among Whippet breeders, Myostatin Deficiency is inherited as an autosomal recessive trait characterized by a heavy muscling effect among dogs with 2 copies of the mutation.

Dogs having 1 copy of the mutation (carriers) may appear to be normal phenotypically but on average possess a greater potential for racing. The carrier canines will also likely pass on the Myostatin Deficiency Mutation 50% of the time, therefore a carrier/carrier mating will likely result in producing “Bully”- affected pups in 25% of the offspring.

DNA results are emailed within five 5 business days, once all samples are received at the laboratory.

Type “Whippet” into the box above to get started or contact us for a free consultation.

Your Myostatin Deficiency DNA-test kit includes:

  • Sterile DNA-collection swabs
  • Complete instructions
  • Postage-paid return envelope (if mailed in the U.S.)

Understanding Results

There are 3 possible genotypes reported for Myostatin Deficiency in Whippets:  

  • CLEAR: those having 2 copies of the normal allele and appear to be normal
  • CARRIER: those having 1 copy of the normal allele and 1 copy of the Myostatin Deficiency mutation and appear to be normal
  • AFFECTED: those having 2 copies of the mutation and appear to be more heavily muscled
