The Preserve has partnered with Cornell University to conduct a genetic study of the Nokota. We collected archival data—including DNA records—which connect the Nokota to the Lakota people and the Great Medicine Chief, Sitting Bull. The 94-horse biobank was used to conduct a genomic research study by Cornell’s Baker Institute of Animal Health, lead by Professor Douglas Antczak, VMD, PhD.
We are excited to share that the study’s research team has completed their initial analysis of the Nokota DNA. Last week they presented their findings to 100 equine geneticists, equine industry and breed organization representatives who attended from the United States and 10 other countries worldwide: England, Scotland, Sweden, Netherlands, Belgium, Italy, France, Switzerland, Croatia, Austria, Spain, Colombia, Qatar, Japan, and Australia.

Analysis Results
Here are the main take-aways from their analysis:
- Nokota horses are a distinct breed based on their DNA. The closest similar breed is the Standardbred Harness Horse.
- Nokota horses appear to have exceptionally high frequency of two genetic markers, or DNA variations, compared to other horse breeds.
- The Nokota have inherited identical versions of these two genetic markers from each biological parent.
The second stage of their analysis will include testing more Nokota to determine the extent of the DNA variations within the breed and looking for evidence of what is driving their diversity.
We are so pleased with the progress that Dr. Antczak’s team has made so far and we look forward to sharing their additional findings!
