Dr. Andersson's Work on DMRT3 Gait Gene

Here is an absolutely fascinating video about Dr. Leif Andersson, Uppsala University, and his work on the DMRT3 gene which is determines if a horse exhibits lateral gaits such as tolt/rack and flying pace. This research was sponsored by the harness racing industry in Sweden to find out if genes influence why a trotter may be more likely to break into a canter and thus be disqualified from the race. The researchers quickly turned to study of the Icelandic horse for help with this research.
