Use this coat color genetics tool to estimate the most likely phenotype in dogs, cats, and horses from genotype results. This calculator interprets key loci involved in pigment production, pigment distribution, dilution, and common color patterns. Includes major loci such as E, K, A, B, D, Merle, and white spotting. Includes Orange, Agouti, dilution, dominant white, and white spotting. Includes Extension, Agouti, Cream, Dun, Gray, Roan, and Tobiano. Select the species, enter genotype results, and generate the predicted coat color phenotype. Animal coat color is determined by combinations of genes that regulate pigment type, pigment intensity, and pigment placement. In many species, the main pigments are eumelanin and pheomelanin. Some loci determine whether black, brown, red, or cream pigment is expressed, while other loci modify the pattern or dilute the final color. This animal coat color predictor focuses on commonly tested loci in dog coat color genetics, cat coat color genetics, and horse coat color genetics. The result is a practical, simplified phenotype prediction based on the genotypes entered in the form above. Yes. Many coat colors in dogs, cats, and horses are strongly associated with known genes. When genotype data is available, DNA can often predict the most likely coat color phenotype. Some phenotypes depend on additional modifier genes, incomplete test panels, breed-specific effects, or interactions not included in this calculator. The result is therefore an informed phenotype estimate. This DNA coat color predictor currently supports dogs, cats, and horses using core genotype markers commonly used in animal color testing.Animal Coat Color DNA Predictor
