Summary:
The Kentucky Derby that comes around every year on the first Saturday in May is a reminder to all of us how fast thoroughbred racehorses really are. It has always been a question in relation to scientists as to how Thoroughbreds got their racing gene in the first place. That question has now been answered thanks to Dr. Emmeline Hill and colleagues, School of Agriculture and Food Science, University College Dublin. Hill and team examined the DNA of hundreds of horses, including that of 12 dead Thoroughbreds, examining their skeleton, born between 1764 and 1930. As they did this, they looked for the C gene which controlls the 'speed gene'. They found that the racing gene first showed up in a British mare about 300 years ago.
Critique:
I think this finding is very interesting. I watch the Kentucky Derby every year and when I watch it, it will remind me of this article and where it all started.
Impact:
I think this finding will help scientists better understand the genes of animals and how to track their genetic coding.
