  1. DNA samples were genotyped by allelic discrimination assay for haplotype-specific polymorphisms, including c.2137 TG/CA (CYP2B11-H2) and c.1952 C/T (CYP2B11-H3). Shown are the numbers of dogs with each diplotype and the derived haplotype frequencies. Greyhounds were divided into two groups based on whether they were identified by their owners as dogs registered with the National Greyhound Association (NGA) bred for racing or dogs registered with the American Kennel Club (AKC) bred for other purposes.
