Thoroughbred speed gene has its origins in native breeds

Research by a team of scientists suggests that a variant of the so-called speed gene found in top racehorses can be traced back to a single British mare living around 300 years ago. That mare may have had a similar genetic make-up to today's sturdy native ponies.

A project bringing together researchers from six different institutions indicates that a particular variation of the gene group called myostatin, which is partly responsible for the impressive speed of the world’s highest-performing thoroughbred racehorses, has been present in the lineage of some thoroughbred horses for at least three centuries and may have come from one particular mare
 
The findings, published this week in the online journal Nature Communications, emerged from a study of the DNA of hundreds of living horses – including thoroughbreds and many of the world’s native breeds – as well as ancient DNA extracted from the skeletons of elite historic horses, among them the legendary Eclipse, one of the most famous horses of all time.
 
The research was led by Dr Emmeline Hill, a genomics scientist at University College Dublin (UCD) and Dr Mim Bower, an archaeo-geneticist at the University of Cambridge. The other institutions contributing to the study were Equinome Ltd, the Swedish University of Agricultural Sciences, the Smurfit Institute of Genetics, and the Russian Academy of Sciences.
