HORSE COLOR CHART - Patterns *UPDATED*

---

/Note: If you want to use some genetic codes for your HARPG horses: At the _ you can fill in "what you want"
For example: E_ can be EE or Ee, you can choose if you want your horse to be a chestnut carrier or not.
Rn_ can be RnRn or nRn ("n" stands for "non-roan" in this case. its often the wild-type allele that is the usual phenotype instead of the mutation (roan in this case))
T_ can be TT or nT
Etc.

A _ before a slash, like "_/Rb_", can be any basecolor what you want. For example: E_/aa/Rb_ (and a fully filled example: Ee/aa/nRb) = a black horse with rabicano.

/Note2: KIT gene mutations can produce 4 different patterns: roan, tobiano, sabino1 and dominant white. This means a horse can't carry those 4 patterns at the same time. The KIT gene only has two 'spots' available, so the horse can only carry two alleles. A sabino1 roan can't be dominant white, because it already has _/Sb1Rn on KIT.  

/Note3: Dominant white (or 'White', 'White Spotting') is a term for a group of 25+ white spotting mutations of the KIT gene. Most of them are believed to be lethal when present in homozygous state. The exceptions are: W15 (which produces a complete white phenotype in homozygous state) and W20 (which is a widespread mutation and many horses have been tested to be heterozygous and homozygous for it). There also exist combinations of W5 and W20 (_/W5W20) and W22 and W20 (_/W20W22) These W5W20 or W20W22 horses have a white or near-white phenotype, with W20 boosting the W5 or W22.  

/Note4: Frame Overo can only be heterozygous (_/nO), because homozygous Frame Overo causes Overo Lethal White Syndrome.
