B/- for their black base. The second letter is unknown but that doesn't matter because B is completely dominant over all other B locus alleles. The - could be either B (black), b (chocolate) or b1 (cinnamon).

O/o to make them torties. O/O would be fully red all over, o/o would be zero red. O is co-dominant with o, so with O/o both red and not-red show in splotches. The not-red areas show their black base color from the B locus. Only females can have this genotype because it is sex linked to the X chromosome. (Males can only ever be O/Y aka red, or o/Y aka black. Their brothers are both O/Y.)

D/- for no dilution. Their black and red bases are full color saturation. Again, the second allele on the D locus is unknown because D is completely dominant over d. They could be either homozygous D/D or heterozygous D/d. d/d would make them blue and cream rather than black and red.

S/S for white content. Must be homozygous because they are white on more than 50% of their bodies. Less white would be S/w, no white would be w/w. FULLY white could be either Wd/S OR Wd/w OR Wd/Wd. Their S/S is expressed in imperfect van patterns.

L/- for short hair. Second allele could be L or l, it could be either for the same reasons given for the B and D loci.

Now for something different between the two! Alba's A locus/agouti gene is a/a because her black patches are solid, aka no tabby markings. But because red ALWAYS expresses tabby markings regardless of what the A locus has, we would normally still be able to figure out the modifiers on the A locus. BUT because she has so much white, it masks most of her tabby pattern. We can only kind of see it on her head and tail red patches. Those parts would look the same on either a classic (mc/mc) or mackerel (Mc/mc or Mc/Mc) tabby pattern. Because of this I can't really make a guess for her Mc locus. Ticked tabbies (Ta/Ta or Ta/ta) on the other hand would not show stripes on the tail, at least not on the base of the tail, unless the ticking was heterozygous (Ta/ta) because it has incomplete dominance over non-ticking (ta/ta). So Alba is either Ta/ta or ta/ta. More likely ta/ta but let's say -/ta to be safe.

Ari makes this much easier for me due to her A locus being A/- thus her phenotype expresses her pattern on her black patches as well as her red. (I initially thought she had to be A/a due to her sister being homozygous a/a, but both parents could have been A/a, making A/A AND A/a possible, along with Alba's a/a.) Her agouti modifiers are then ta/ta for no ticking, and Mc/- for a mackerel pattern.

The rest just lays out what they are Not:

Both are C/- for no pointing or albinism.

Both are i/i for no inhibitor gene to make them silver(Ari) or smoke(Alba).

Both are wb/wb for no wide band gene to make them golden (or chinchilla).

All hair texture loci are N/- because they aren't rexed, hairless, curled, nor do they have less follicles (such as in the lykoi breed).

pd/pd for no polydactyly.

fd/fd and cu/cu for no foldie or curled ear genes.

m/m and jb/jb for no manx or bobbed tail genes.
