Thoroughbred Racehorse Mitochondrial DNA Demonstrates Closer Than Expected Links Between Maternal Genetic History And Pedigree Records

Thoroughbred Racehorse Mitochondrial DNA Demonstrates Closer Than Expected Links Between Maternal Genetic History And Pedigree Records: Pedigree analysis is one of the main methods used to ascertain future potential for racing performance. Despite the importance of pedigree, there is some doubt as to the voracity of historic pedigrees. This study found that, in fact, maternal sub-lineages represent a more accurate breeding record than previously thought.
