Mongolian horses show close genetic links to northern European breeds, suggesting ancient gene flow. This indicates eastern horse populations likely influenced the genetic makeup of northern European horses.

Area of Science:

  • Animal Genetics
  • Population Genetics
  • Equine Genetics

Background:

  • Human migration historically facilitated the movement of livestock, including horses.
  • Central Asian populations have genetically influenced northern European human populations.
  • Potential for parallel gene flow in livestock, specifically horses, from east to north Europe.

Purpose of the Study:

  • To investigate the genetic relationship between Mongolian native horses and northern European horse breeds.
  • To determine if genetic material from eastern horses contributed to northern European horse populations.

Main Methods:

  • Analysis of microsatellite data to calculate genetic distances (DA and (deltamu)2).
  • Construction of phylogenetic trees to visualize genetic associations.

  • Comparison of genetic distances between Mongolian, northern European, and southern-derived horse breeds.

    • Main Results:

    • Microsatellite data revealed close genetic associations between Mongolian native horses and northern European breeds.
    • Genetic distances were significantly larger between northern European breeds and southern-derived breeds (Standardbred/Thoroughbred).
    • Phylogenetic analyses supported the close relationship between eastern and northern European horse populations.

    Conclusions:

    • Evidence suggests a significant contribution of genetic material from eastern horses to northern European horse breeds.
    • The findings align with historical human migration patterns carrying livestock.
    • This study highlights the impact of ancient gene flow on the genetic diversity of European horse populations.
