I just got my genetics kit in the mail for Cornell University's horse size study. If you'd like to participate email equinegenetics@cornell.edu

You'll be asked to take hair samples of your horse and to make 35 different measurements on your horse.  They provide a return envelope, detailed directions and even the tape measure to use!  They need 1000 horses for this study.  They'd live everything from minatures to shires as they try to figure out what genes are responsible for size of a horse.
