Tricolor Coat
The Beagle is a hound breed with a tricolor coat that typically consists of black, white, and tan colors. The exact pattern varies, but the combination gives Beagles their distinctive appearance.
Genetic Basis
Coat color is largely determined by genetics. The Extension locus controls black pigment, the Brown locus controls brown pigment, and the White Spotting locus controls white markings. Interactions between these genes and modifiers produce the specific patterns seen in Beagles.
