Notice that this is just an example list on how to use genotypes.
This list is rather standardtized and not 100% accurate or complete.


How we determine foal genes:
EE x EE = EE
EE x Ee = EE or Ee
Ee x Ee = Ee or EE or ee
Ee x ee = Ee or ee
ee x ee = ee

A+ x A+ = A+ (no matter what other agouti gene horse has)
AA x AA = AA
AA x Ata = AA or AAt or Aa
AA x Aa = AA or Aa
AA x aa = Aa
AtAt x AtAt = AtAt
AtAt x Ata = AtAt or Ata
AtAt x AtA = AtAt or AtA
AtAt x Aa = AtAt or Ata or AAt
AtAt x aa = Ata
Ata x Ata = AtAt or Ata
Aa x Aa = AA or Aa or aa
Aa x aa = Aa or aa
aa x aa = aa

GG + GG = GG
GG + Gg = GG or Gg
GG + no grey = GG or Gg
Gg + Gg = GG or Gg or no grey gene
Gg + no grey = Gg or no grey gene

CrCr x CrCr = CrCr
CrCr x nCr = CrCr or nCr
CrCr x no cream = nCr
nCr x nCr = nCr or no cream gene
nCr x no cream = nCr or no cream gene

RR x RR = RR
RR x nR = RR or nR
RR x no roan = nR
nR x nR = nR or no roan gene
nR x no roan = nR or no roan gene

DD x DD = DD
DD x nD = DD or nD
DD x no dun = nD
nD x nD = DD or nD
nD x no dun= nD or No Dun

RbRb x RbRb = RbRb
RbRb x nRb = RbRb or nRb
RbRb x no rabicano = nR
nRb x nRb = nRb or no rabicano gene
nRb x no rabicano = nRb or no rabicano gene

SplSpl x SplSpl = SplSpl
SplSpl x nSpl = SplSpl or nSpl
SplSpl x no splash = nSpl
nSpl x nSpl = nSpl or no splash gene
nSpl x no splash = nSpl or no splash gene

SbSb x SbSb = SbSb
SbSb x nSb= SbSb or nSb
SbSb x none sabino = nSb
nSb x nSb= SbSb or nSb
nSb x none sabino = nSb or no sabino gene

ZZ x ZZ = ZZ
ZZ x nZ = ZZ or nZ
ZZ x no silver = nZ
nZ x nZ = nZ
nZ x no silver = nZ or no silver gene

TbTb x TbTb= TbTb
TbTb x nTb= TbTb or nTb
TbTb x none tobiano = nTb
nTb x nTb= TbTb or nTb or no tobiano gene
nTb x none tobiano = nTb or no tobiano gene

OO = deceased horse, lethal combination
nO x nO = deceased or nO
nO x non overo = nO or no overo gene

WW = deceased horse, lethal combination
nW x nW = deceased or nW
nW x non white = nW or no white gene

LpLp x LpLp= LpLp
LpLp x nLp= LpLp or nLp
LpLp x none appaloosa = nLp
nLp x nLp = LpLp or nLp or no appaloosa gene
nLp x none appaloosa = nLp or no appaloosa gene

ff x ff = ff
ff x nf = ff or nf
nf x nf = ff or nf or no flaxen gene
ff x none flaxen = ff or nf
nf x none flaxen = nf or no flaxen gene
(Notice - flaxen only shows on horse if *ff*)

StySty x StySty = StySty
StySty x nSty = StySty or nSty
StySty x no sooty = nSty
nSty x nSty = nSty
nSty x no sooty = nSty or no sooty

ChCh x ChCh = ChCh
ChCh x nCh = ChCh or nCh
ChCh x no champagne = nCh
nCh x nCh = nCh
nCh x no champagne = nCh or no champagne gene

prlprl x prlprl = prlprlprl
prlprl x nprl = prlprl or nprl
prlprl x no pearl = nprl
nprl x nprl = nprl
nprl x no pearl = nprl or no pearl gene

Examples on use:
Stallion: ee Aa Gg nD ff
Mare: Ee Ata nCr nf nSty

Foal: ee Ata Gg nD ff
just for general use.
