Brindle coloration is a fascinating black and brown pattern that appears on dogs, cats, and cows. This striking pattern is caused by a genetic code at the "K locus," which is believed to be controlled by a gene called ASIP. This gene is crucial in controlling pigment switching, determining whether an animal will have black or brown pigmentation. A unique combination of alleles at the K locus in brindle animals results in our stunning black and brown stripe pattern.
