How can I tell after I do a gene test? |

Homozygous means the "same zygotes"
Home = Same
Zygous = Zygote
Heterozygous means the "different zygotes"
A zygote is basically a fertilized egg, and I won't go too far in depth to that because it would be going even further from your question.
To tell if a gene is homo or hetero, you look for what is the same and what is different.
A homozygous gene would either be all capitals, or all lowercase lettering. A heterozygous gene would have a mix.
Homo:
Extension: EE or ee Agouti: AA or aa Creme: CC or cc Roan: RnRn or rnrn Dun: DD or dd Pearl: PrlPrl or prlprl Silver: ZZ or zz Champagne: ChCh or chch Grey: GG or gg White: WW or ww Tobiano: ToTo or toto Splash White: SplSpl or splspl Sabino: SbSb or sbsb Rabicano: RbRb or rbrb Frame: OO or oo Leopard Complex: LpLp or lplp PATN-1: PATN-1PATN-1 or patn-1patn-1 PATN-2: PATN-2PATN-2 or patn-2patn-2
Hetero:

**Brindle isn't accounted for because it's either X+ (Brindle) or X- (No Brindle) |
