Color is among some of the earliest traits we selected in newly domesticated species (1). Today, color can be critical for registration and therefore, the value of our horses. For example, in breeds like the Friesian (which requires true black) and the exotic Mangalarga Marchador (which does not allow cremellos or perlinos) color is more than an aesthetic preference, it is a breed requirement. Indeed, on average, presence of a spotting pattern doubles the value of an APHA foal. For example, in 2006, the average price of an American Paint Horse Association (APHA) registered yearling without a spotting pattern was $1540, while a yearling APHA registered horse with the tobiano pattern averaged $2803 (2).

Can Genetics Turn the Art of Stallion Selection into a Science?
February 03, 2016
The horse genome contains all the information required to direct the growth and function of a foal, from conception to death. This enormous “text” is organized into chromosomes, much like the volumes of an encyclopedia. The domesticated horse possesses 32 unique chromosomes, and most cells carry two copies of each chromosome for a total of 64. Gametes of course are the exception, carrying just one of each of the chromosome pairs to the future offspring. This article will discuss information about genotype vs. phenotype, genetic testing, and recent genetic studies performed on stallions.
