Online tools designed to predict equine coat color inheritance analyze genotypes of parent horses based on known coat color genes and their alleles. For example, inputting genetic information for a chestnut mare and a bay stallion allows the tool to predict the probabilities of various coat colors in their offspring, such as bay, black, or chestnut.
Such predictive tools offer valuable insights for breeders seeking specific coat colors. By understanding the genetic basis of coat color inheritance, breeding decisions can be made more strategically. Historically, predicting offspring coat color relied on observation and pedigree analysis, which could be less precise. These modern tools represent a significant advancement in equine breeding practices, offering more informed choices and potentially reducing the occurrence of undesirable coat colors.
