Questions will be kept anonymous on request. Areaderasks: Could you explain what is meant by a gray factor m breeding horses? What color or breed combination will give the most possibilities of having a gray foal? P. Kauffman, Pequea Dr. Sheaffer comments: The gray factor is present in most breeds of horses and very prominent in two breeds - the Arabian and the Percheron. The color is due to the presence of a genetic trait for gray coat color. For example, a gray horse must have at least one dominant gene for the gray color. Gray color is recessive to both bay Grand champion Chester County 4-K market lamb, left photo, shown by Donna MacCauley, Atglen, was purchased by Mrs. Cloud, of the Southeast National Bank of Atglen, for $2.06 a pound.

Tim Trayer Edgar Sheaffer and chestnut coat color. It may also be recessive to brown and black. A homozygous gray will carry two dominant genes for the coat color. Certain outstanding Arabian stallions are homozygous grays. Most of the foals born to homozygous gray parents are gray at birth or will turn gray sometime during life. However, many Arabian horses are heterozygous for coat color. For example, a bay colored horse has a bay phenotype (visible color) but may carry genes for both bay and gray coat color (genotype). If you breed two parents with a heterozygous genotype, you have a 25 percent chance of getting the recessive color (gray) and at least a 50 percent chance of the first generation foal carrying the recessive color regardless of his phenotype. The best parental cross for gray phenotype would be to use two gray horses especially if one parent is known to be homozygous in genotype. A second best cross would DEUTZ DIESELS FROM INDIANA?
