Summary

This webinar, presented by Margo Colin, head of the genomics platform at LABÉO, explains the genetic basis of horse coat colors and the importance of genetic testing. It begins with the basics of genetics, including inheritance, DNA, and mutations, and how they relate to coat color. The presentation covers base colors (bay, black, chestnut) determined by the Extension and Agouti genes, and then discusses dilution genes such as Cream, Pearl, Champagne, Dun, and Mushroom, which modify these base colors. It also addresses white patterns (Pinto, Sabino, Splash White, and Lethal White Overo) and their associated health risks. The speaker emphasizes the practical applications of genetic testing for breeders, including predicting foal colors, avoiding lethal combinations, and complying with breed registries. The webinar includes visual examples of foals and adult horses to illustrate how coat colors change with age and how to identify them. The presentation concludes with a Q&A session, but the transcript provided does not include the questions or answers.
