title: Usefulness of lymphocyte typing to exclude incorrectly assigned paternity in horses.
abstract: Lymphocyte typing can be used to detect incorrectly identified parentage of horses. Efficacies of lymphocyte typing to solve paternity questions were calculated using gene frequency estimates of equine lymphocyte antigen (ELA) markers for Thoroughbreds and Standardbreds. Probabilities that ELA typing will detect an incorrectly assigned sire were 68.7% in Thoroughbreds, 67.9% in pacing Standardbreds, and 62.0% in trotting Standardbreds. These calculations demonstrate that ELA typing is among the most efficacious genetic systems for solving paternity questions in horses. Likewise, it could also be effective for blood type identification and solving other questions of parentage in horses.
