Equine color genetics follow similar rules, but because we’re talking genetics, there are a few wild cards thrown in for good measure. Genotype refers to the horse’s genetic makeup. –A homozygous genotype is two Coat color patterns are created by genes. Each gene is made up of two alleles. two horses. Each paint horse has a particular combination of white and any color of the equine spectrum. Horses’ coat colors are derived from one of two possible base pigments: red or black, which means that every horse has a gene for either of these pigments. We no longer perform the serum protein test based on blood types due to its low reliability. Because e is recessive, the only A black horse's genetics will always read EE aa or Ee aa for the base color. No genetic markers associated Breeders consider those wild cards part of the thrill in breeding color horses. Color genetics is the study of the genes behind coat colors. base coat colors. Since the tobiano color pattern is valued and is dominant, horses that possess two copies of the gene (homozygous) are of special value to breeders, as ALL their offspring will inherit the tobiano color pattern.

To date, scientists have identified 12 distinct dominant white mutations. The gene is acting semi-dominant, with homozygotes showing a more extreme phenotype than heterozygotes. Many other white patterns appear as and inherit as sabino but have no test. Breeders and owners can put the power of genetic testing to work with a quick and easy DNA test. However, the most exciting thing is that they have distinctive white markings in physical body coloring. Overo is a Spanish word, originally meaning "like an egg".There are at least three genetically different spotting patterns which fall under the "overo" classification: frame overo, sabino … Paint horses with roan coloring can have large areas of white with colored areas that contain the roan pattern.
