Probing pedigrees

Thank you for carrying so many articles by Deb Bennett, PhD (Conformation Insights). They are always fascinating and thought-provoking. I have especially enjoyed her five articles on the Thoroughbred breed. I bought a young Quarter Horse who has a good portion of Thoroughbred in him, probably more than actual Quarter Horse. It’s given me many hours of pleasure to compare Dr. Bennett’s breeding lines with those I find in my horse’s pedigree. He looks very little like a Quarter Horse and most people assume he’s Thoroughbred.
