I have a blue roan tobiano I'm planning to register and I'm terrible with genetic alleles. Would anyone mind giving me a hand? Thank y'all in advance!

Do you need his genotype? His genotype could be either aa/Ee/nT/Rr or ee/EE/nT/Rr. The EE or Ee depends on if you want him to be a red carrier or homozygous black. Ee is red carrier, EE is homozygous black.

There are many, many variations for that coat color depending on the dominance of each gene. If you want the genotype that will have the most foal color possibilities it'd would be: Ee/aa/nT/nRn
Variations:
Homozygous black (will always produce black or blue roan colored foals) is: EE/aa/nT/nRn
Homozygous Tobiano (will always produce tobiano foals) is: + Ee/aa/TT/nRn (this horse will always produce a tobiano foal, with a chance of roan, as well as a chance of either black or red variation) + EE/aa/TT/nRn (this horse will always produce black tobiano horses, with a chance of roan depending on the other parent)
Homozygous Roan (will always produce a roan foal) is: + Ee/aa/nT/RnRn (this horse could have red roan foals with a chance of tobiano in either black or red variation) + EE/aa/nT/RnRn (this horse will always have blue roan foals with a chance of tobiano) + Ee/aa/TT/RnRn (this horse will always have roan tobiano foals; in either black or red variations) + EE/aa/TT/RnRn (this horse will always have blue roan tobiano foals)
