The next thing I do is multiply the individual outcomes together and make sure I get the same number as the number of possibilities that the game said I had, to make sure I didn't make a mistake. 2^8 = 256, so I'm good here. Then I find and replace genes in my default strings where the recessive version is not an outcome (Agouti and PATN-2 here).

What I like to do is go gene by gene. I hope I can make my method make sense. I’ll use today’s horses as my example.

Today’s Sire: ee,AtAt,CC,rnrn,Dd,PrlPrl,zz,chch,gg,ww,toto,splspl,sbsb,rbrb,oo,lplp,patn-1patn-1,patn-2patn-2

Today’s Dam:
Ee,AA,CC,Rnrn,Dd,PrlPrl,zz,chch,gg,ww,Toto,splspl,sbsb,Rbrb,oo,LpLp,PATN-1PATN-1,patn-2patn-2

1.) For each gene, we take one from each parent. Starting with Extension (E or e), the combinations we can get for this sire and dam are “Ee” and “ee”. Our starting lines are going to be:

Ee

ee

2.) Next we have agouti and cream, which both only have one possible combination from these parents - “AtA” and “CC”. We add those to the two starting lines, and now we have:

Ee,Ata,CC

ee,Ata,CC

3.) For roan, we’re back to two possible combinations - “rnrn” and “Rnrn”. What we’re going to do now is copy/paste the two starting lines, so both possibilities are accounted for in both ways:

Ee,Ata,CC,rnrn

ee,Ata,CC,rnrn

((Showing separation))

Ee,Ata,CC,Rnrn

ee,Ata,CC,Rnrn

4.) For dun, we now have three possible combinations - “dd”, “Dd”, and “DD”. Just like before, we’re going to copy/paste, but now we’re going to have three total copies:

Ee,Ata,CC,rnrn,dd

ee,Ata,CC,rnrn,dd

Ee,Ata,CC,Rnrn,dd

ee,Ata,CC,Rnrn,dd

((Showing separation))

Ee,Ata,CC,rnrn,Dd

ee,Ata,CC,rnrn,Dd

Ee,Ata,CC,Rnrn,Dd

ee,Ata,CC,Rnrn,Dd

((Showing separation))

Ee,Ata,CC,rnrn,DD

ee,Ata,CC,rnrn,DD

Ee,Ata,CC,Rnrn,DD

ee,Ata,CC,Rnrn,DD

5.) Pearl (PrlPrl), silver (zz), champagne (chch), grey (gg), and white (ww) all only have only possible combination. That means we can add them all to the end of the framework we have now:

Ee,Ata,CC,rnrn,dd,PrlPrl,zz,chch,gg,ww,

ee,Ata,CC,rnrn,dd,PrlPrl,zz,chch,gg,ww,

Ee,Ata,CC,Rnrn,dd,PrlPrl,zz,chch,gg,ww,

ee,Ata,CC,Rnrn,dd,PrlPrl,zz,chch,gg,ww,

Ee,Ata,CC,rnrn,Dd,PrlPrl,zz,chch,gg,ww,

ee,Ata,CC,rnrn,Dd,PrlPrl,zz,chch,gg,ww,

Ee,Ata,CC,Rnrn,Dd,PrlPrl,zz,chch,gg,ww,

ee,Ata,CC,Rnrn,Dd,PrlPrl,zz,chch,gg,ww,

Ee,Ata,CC,rnrn,DD,PrlPrl,zz,chch,gg,ww,

ee,Ata,CC,rnrn,DD,PrlPrl,zz,chch,gg,ww,

Ee,Ata,CC,Rnrn,DD,PrlPrl,zz,chch,gg,ww,

ee,Ata,CC,Rnrn,DD,PrlPrl,zz,chch,gg,ww,

***

With that, all the possible variations of adding to the framework have been covered. Each gene can have from 1-3 combinations, which you add to the end of possibilities you’ve calculated so far. If you continue the chronological pattern of copying/pasting the growing framework to account for different combinations per gene, you’ll end up with a complete list of all possibilities!
