Click here to input what you know about your mare and the color genetic information of the stallion you are thinking of breeding to and figure out what color your foal could be.   email Tina at thelewisranch@aol.com if you need help figuring out what your mare's color genetics are if you have not had her tested-you can also use "unknown". Color genetics of my stallions: none are gray or carry the silver gene Shiners Dew  is homozygous for the black gene (EE), no creme or Agouti (aa) and no red gene Mr FL Fancy Pants  is homozygous for Tobiano (TT) so a paint will always result but his coat color is buckskin, has red and black genes (Ee) and one creme gene as well as Agouti (Aa) Bueno Blue Badger  is homozygous for the black gene (EE), carries dun factor (Dd) and carries one cream gene and no Agouti (aa), he will never sire a sorrel and never sire a bay unless the mare carries and throws the Agouti gene to restrict the black he throws to points. GWS Lenas Drifter  is a homozygous red roan (Rn/Rn).   He carries the red gene (ee) and no black gene and is also homozygous for Agouti (AA).  No creme gene Dun It Dealin  is a Dunskin (Buckskin/dun).  He carries one cream gene, one red and one black gene (Ee) and carries one dun gene (Dd) and one Agouti gene (Aa) Just Plain Primo is a bay.  He carries one black and one red gene (Ee) and one Agouti gene (Aa), no cream and no dun genes. Frozen semen stallions: Ace O Lena is a sorrel son of Doc O 'Lena.  He carries two red genes (ee), no dun, no cream, no black...he may carry Agouti but isn't going to be expressed unless mare throws black Msf Royal Cheifton  is homozygous for Tobiano so a paint will always result, his coat is black but  he carries both red and black genes with no Agouti (aa),  and no creme or dun Doublesmokinfreckolena  is a Tobiano that is not homozygous for that gene (Tt), he is chestnut (ee) and carries no Agouti, cream or dun.

Single Dilute   Palominos & Buckskins: Both of these colors are caused by the cream gene, generally denoted by the letter C ("Cc" for heterozygotes / single dilutes and "CC" for homozygotes / double dilutes). Palomino is cream acting on a chestnut base coat, and buckskin is on a bay base coat. Black horses with the cream gene are termed "smokey blacks," but there is little, if any, visually detectable difference between a non-dilute black and a smokey black. The cream gene dilutes only the red, or chestnut, pigmentation in a horse's coat, which is why buckskins retain their black mane and tail and why blacks are not affected at all.  This gene is incompletely dominant, meaning it takes two copies of the gene to reach its full expression. Buckskins, palominos, and smokey blacks carry only one copy (Cc).                                                                             Double Dilute Perlinos & Cremellos:  A chestnut horse with two copies of the cream gene (CC) is called a cremello, and is much lighter than a palomino. A bay with two copies of the gene is called a perlino, and the color difference here is even greater than between palominos and cremellos. Unlike smokey blacks, black double dilutes (called smokey creams) do have a diluted appearance. The cream gene in its homozygous state (perlino/cremello/smokey cream)dilutes not only red pigment, but black as well. Two key differences between single (palomino/buckskin) and double dilutes (cremello/perlino/smokey cream) are that all double dilutes have blue eyes (the eyes of single dilutes are not affected by the gene), and all double dilutes have pink skin (single dilutes retain dark skin).  The creme gene does not affect roan.  But will dilute the base color of a roan horse.

Duns & Grullas: Dun (and grulla - also spelled "grullo", which is dun on black) is also a diluting gene that acts mostly on red pigment (though black is slightly diluted, as can be seen with grullas). Unlike cream, however, dun is completely dominant (i.e. only one copy of the gene is necessary for full expression), and there is no difference in appearance between heterozygotes (Dd) and homozygotes (DD). Duns, especially bay duns, are often mistaken for cream dilutes (buckskins), as their coloring is similar (to make things ever more confusing, a horse can possess both the dun gene AND the cream gene - see examples below), but there are certain distinct traits that set duns apart. These are known either as "dun factors" or "primitive markings." The most easily recognizable is a distinct dorsal stripe. While any horse can have a dorsal stripe, the dorsal stripe of a dun tends to be very dark and have crisp, hard edges, giving it a "painted on" look. This can be seen in the lower picture to the left. A second dun factor, sometimes difficult to see depending on how much black there is on the legs, is leg barring. Duns have several horizontal stripes across each of their legs, usually ranging from slightly below to slightly above the knee area. The third dun factor is shoulder baring or shoulder "masking," which is not always present. Often a dun will have one or two short vertical "bars" radiating down from the dorsal stripe over the shoulders.   The Lewis Ranch   Equine Color Genetics
