Many DNA sequence variations are fine; they just give rise to the broad spectrum of colors, sizes, and other characteristics we see in the horse population. Some variations, however, cause problems. These might range from a genetic predisposition
A San Francisco, Calif., company announced in late July its intention to clone one individual’s horse for profit, at a cost of $367,593 for implanting clone embryos into 100 mares plus additional patent royalties based on the number of clones
Glycogen-branching enzyme disorder (GBED) has likely been a cause of neonatal mortality in Quarter Horses for decades, according to Stephanie Valberg, DVM, PhD, who gave an update on her research on the disorder at the recent conference of the
Equine researchers around the world are gearing up for the sixth International Equine Genome Workshop, to be held in Dublin, Ireland, this summer. The meeting will allow participating scientists to move one step closer to achieving their
How likely is it that arthritis will be passed on from a mare to her offspring?
Wobbler, also known as wobbles, takes its name from its primary sign–a wobbling or uncoordinated gait. In technical terms, the horse has a “proprioceptiveness deficit,” or a lack of physical awareness of his limbs and their placement.
The American Quarter Horse Association’s (AQHA) statement regarding hyperelastosis cutis (HC) or hereditary equine regional dermal asthenia (HERDA):
1. AQHA is aware of the condition known as hereditary equine regional
I hear people talking about how genetic lines all trace through the paternal side of the horse. What about the mares?
In October 2002, a meeting of the Interagency Working Group for domestic animal genome sequencing was convened at the USDA Whitten Building in Washington DC to discuss prioritization of domestic animal species for DNA genome sequencing. That suc
In October 2002, a meeting of the Interagency Working Group for domestic animal genome sequencing was convened at the USDA Whitten Building in Washington, D.C. to discuss prioritization of domestic animal species for DNA genome sequencing. That
British scientists have identified the distinctive gene that gives about 3% of the Thoroughbred population the gray coat color, and they plan to continue studying the genetics in hopes of learning why grays are more prone to developing melanomas
Cremellos or perlinos, which are horses that exhibit light or pink skin over the body, white or cream-colored hair, and blue eyes, might be eligible for registration in the American Quarter Horse Association (AQHA). Last week, the AQHA Stud Book
The horse genome effort received a major boost in April 1998 when the United States Department of Agriculture (USDA) approved renewal of an initiative of the National Animal Genome Project which, for the first time, includes support for
DNA testing replaces blood typing as the Arabian Horse Registry of America’s required tool for verification.
It was previously thought that modern horses were descended from a limited number of wild herds and were selectively bred, leading to the diversity in breeds that we have now. However, new DNA evidence suggests that horses have a more diverse
The solution to health and soundness problems facing horses might be as close as the horse itself. Laminitis, colic, respiratory disease, and even joint problems could be prevented or treated using genetics. At the Blue Ribbon Horse Genome
