Estonian Native Horse and genetics

 Salvete Omnes,

while perusing academia.edu subscriptions and searching for the Birka warriors etc I came across Gus Cothran's page on academia. 
I guess I started my adventure with horse genomics by reading prof. Cothran's articles etc.
So in his(and esteemed colleagues)  2019AD article -  Population Genetic Analysis of the Estonian Native Horse Suggests Diverse and Distinct Genetics, Ancient Origin and Contribution from Unique Patrilines- (link) we have a study of the Estonian Native Horse -    University of Oklahoma livestock and breeds page - wiki page, breeders pages. 

The horse averages 147cm at withers and about 430kg in weight (I guess the stallions). Its gene pool includes Mongolian horse and the Yakutian; Scandinavian horses like Gotland Pony, Norvegian Fjord, and Islandic Pony; British Isles horses - Exmoor and Shetland,  Polish Konik and Carpathian Hucul... 

This small horse might have been part of the horses' pool used by the Polish-Lithuanian Commonwealth armies as between 1569-1629 Duchy of Livonia was part of our Polish state. Also, it is reasonable to infer that some Polish stallions left their progeny among the herds of the Estonian horse during that period.  After 1620s the Duchy of Livonia was conquered and annexed by the Swedes who already held the northern part of Estonia. It all ended with Peter the Great of Imperial Russia conquering all of Estonia during the Great Northern War. And Estonian horse became popular in Imperial Russia.. and so on until the present it is the native breed in the independent Estonia.
