Fawn Coat Gene Calculator

Ever wondered what possibilities might come from combining certain genotypes? Well, wonder no more! This calculator was built to help you figure out what genes can be passed from parent to offspring. All you need to do is select from each locus below the genes belonging to the potential sire and dam.


If the parent does not have one of the genes in the loci listed below, simply select n/n to represent that they do not have that locus.


Please note that this was created with RoE’s specific gene system in mind, so it may not work for other breeds or species similarly based on horse genetics.
