Hypothesis
What are the maternal origins of Thoroughbred foundation mares?
Conclusion
Thoroughbred foundation mares had a cosmopolitan European heritage with significant contributions from British and Irish native mares.
Supporting Evidence
- Thoroughbreds showed extensive haplotype sharing with Eurasian domestic horses.
- The estimated contribution of British and Irish Native horses was 61 percent.
- Thoroughbreds had greater affinity to British and Irish Native breeds than Oriental horses.
Takeaway
The study found that the mothers of Thoroughbred racehorses came from many different places in Europe, especially from British and Irish horses, not just from the Middle East.
Methodology
Mitochondrial DNA was analyzed from 1929 horses to trace maternal lineages.
Potential Biases
Potential bias in historical records regarding the importance of female horses.
Limitations
The study cannot precisely determine the contributions from specific European horse populations.
Participant Demographics
The study included Thoroughbred horses and various British Native breeds.
