The vast array of coat patterns and interesting pigmentation variations exhibited by horses that CSNB stands for congenital stationary night blindness. If a horse has at least one LP allele, it will display at least some appaloosa characteristics. In return, we help you with the practical application of our findings. The following diagram shows the coat pattern range for horses with the LP gene. Its possible for two registered, spotted Appys to produce a solid foal, and the registry allows for this. The PATN1 mutation has been found in other breeds but may not have an effect on phenotype in the absence of LP. In this cultural context, Appaloosas symbolize a proud heritage, adaptability, and the close bond between humans and horses.
