Very nice!! I'm not sure how much you know so feel free to ask for a more in-depth explanation if you need!

Red - For a horse to be red, it needs to have the red allele "e" on the Extension gene. Red is a recessive colour, so it will need two copies to 'work'; this horse must be "ee". Red horses can't produce black pigment, so it can carry any alleles on the Agouti gene without the coat colour being affected. It could be ee/AA, ee/aa, ee/AtA+, etc., it would have no visual effect :)

Roan - Roan is a complete dominant gene. This means that regardless of whether there are one or two copies, the horse's coat will look the same. So this horse could be Rnrn (one copy) or RnRn (two copies).

Tobiano - Like roan, it's dominant (although there's some evidence that expression changes depending on one or two copies). This horse could be TOto or TOTO.

Some example genotypes for this horse (there are more!):
ee/Ata/TOto/RnRn
ee/aa/TOTO/Rnrn
ee/A+A+/TOto/Rnrn
ee/Aa/TOTO/RnRn

oh wow, thank you so much arkin!! hoping to do more studies on equine genotypes, so this definitely was a great explanation. thank you again<3

No problem! I'm currently writing up a guide with sources here, it's not even close to done but you may like to keep an eye on it x)
