Base color - the solid underlying coat, the three base colors are Chestnut, Black, or Bay

-------------

Cream gene - this is the C gene in horses, it creates the sub colors of the bases. Cream will dilute the Red gene as seen below, but the black is not effected. Here's a quick list and explanation:

cc - the horse has no cream but carries the gene anyway
Crc - the horse has one copy of the cream gene
CrCr - the horse has 2 copies of the cream gene

-------------

+ cc= no visible cream
+ Cr = (with bay is buckskin), (with red is palomino), smoky black
+ CrCr = Cremello, Perlino, Smoky Cream

-------------

Agouti and Extension genes - this is the A and E genes in horses, it creates the sub colors of the bases. Here's a quick list and explanation:

aa - the horse has no red if E is present, is red if E is absent
Aa - the horse has one copy of the red gene
AA - the horse has 2 copies of the red gene

ee - the horse has no black
Ee - the horse has one copy of the black gene
EE - the horse has 2 copies of the black gene

-------------


AA EE is bay
Aa Ee is bay
AA Ee is bay
Aa EE is bay

EE aa is black
Ee aa is black

ee aa is red
ee Aa is red
aa AA is red

-------------

Roan gene - this is the Rn gene in horses, it creates the sub colors of the bases. Here's a quick list and explanation:

rnrn - the horse has no roan but carries the gene anyway
Rnrn - the horse has one copy of the roan gene
RnRn - the horse has 2 copies of the roan gene

-------------

+ rnrn = no visible roan
+ Rnrn = is a roan but will not always have roan foals
+ RnRn = is a roan and will always have roan foals

-------------

Pearl gene - this is the Prl gene in horses, it creates the sub colors of the bases. Here's a quick list and explanation:


+ prlprl = is pearl
+ Prlprl = carries pearl
+ PrlPrl = is not pearl

Pearl can interact with the cream gene, when this happens its called a Pseudo-double dillute, this will only effect horses with CCcr or one copy of the cream gene. This can cause a horse to have blue or green eyes!

-------------

Silver gene - this is the Z gene in horses, it creates the sub colors of the bases. Here's a quick list and explanation:

zz - the horse has no silver but carries the gene anyway, Chestnut cant be silver.
Zz - the horse has one copy of the silver gene, the mane and tail are lightened
ZZ - the horse has 2 copies of the silver gene

-------------

White gene - W


--------------

Grey/Gray gene - G
will slowly make a horse whiter in color, but they will remain a grey because of their skin

-----------

Dun gene - D

there is typically a dorsal or primitive

------------------

ToTo - Tobiano, always foals tobiano
Toto - tobiano, sometimes foals tobiano
toto - not tobiano, cant contribute to making a tobiano foal unless the other parent is ToTo or Toto
Oo - Overo
oo - not overo
OO - lethal white, can kill a foal
SbSb - sabino horse, always has sabino foals
Sbsb - sabino horse, sometimes has sabino foals
sbsb - not sabino, cant contribute to making a sabino foal unless the other parent is SbSb or Sbsb

---------------

LpLp - un-spotted appy, has snowcap or other forms of blankets without the spots
Lplp - spotted appy

lp/lp n/n.......................Non Appaloosa, will not pass on LP or PATN1 to offspring.
lp/LP n/n.......................Heterozygous LP horses will pass the to 50% (blanket appaloosa).
LP/LP n/n......................Negative for PATN1 (snow cap appaloosa).
lp/lp n/PATN1................Non Appaloosa, will not pass on LP. Will pass on PATN1 50% of the time.
lp/LP n/PATN1................Produces a leopard or a near–leopard pattern.
LP/LP n/PATN1...............Results in a few-spot or near few spot pattern.
lp/lp PATN1/PATN1............Non Appaloosa, will not pass on LP but always PATN1 to offspring.
lp/LP PATN1/PATN1............Produces a leopard or a near–leopard pattern.
LP/LP PATN1/PATN1.............Results in a few-spot or near few spot pattern.

NOTE:
Chimera is NOT genetic, it is the rare fusing of two embryos this why the horse is double colored. Dapple is NOT genetic, but sooty is! Pangare is NOT genetic. Bend Or, Belton, Ermine, and Birdcatcher are NOT genetic. Corn/Grease Spots are typically formed over cuts and thus are not genetic. Markings (plain, ie snip or a sock on a certain leg, not caused my paint genes) are NOT genetic. Mismarkings are typically NOT genetic.

if you have any question id be happy to help. note that this is how I do my genes, what I consider not genetic can totally be for your breed on here, thats ok, thats original, i am talking more so irl.
