Dilution Genes
In the case of horse color, dilution means less concentrated
color, which means lighter color. Genes always come in pairs, in animals
that need two parents to produce an offspring...one from each parent.
 | Cream
 |
The Cream gene is abbreviated "Cr" in genetic
symbols. The gene for absence of Cream is abbreviated "cr". |
|
The Cream gene is an INCOMPLETE DOMINANT gene.
This means if one gene is present, it will show (manifest) one way,
and if two copies are present, it will show (manifest) differently |
|
One Cream gene will lighten the base colors to colors
such as palomino or buckskin |
|
Two Cream genes will lighten the base colors to colors
such as cremello or perlino |
|
| Dun
|
The Dun gene is abbreviated "D" (or sometimes
"Dn") in genetic symbols. The gene for absence of Dun is
abbreviated "d". |
|
The Dun gene is a SIMPLE DOMINANT gene. This means
that if one gene is present it will manifest fully, and if two are
present it manifests no differently than with one. |
|
The Dun gene lightens the body color and leaves stripes of
the original color along the back and on the upper legs, and often
other places as well.) |
|
| Champagne
|
The Champagne gene is abbreviated "Ch" in
genetic symbols. The gene for absence of Champagne is abbreviated
"ch". |
|
The Champagne gene is a SIMPLE DOMINANT gene. This
means that if one gene is present it will manifest fully, and if two are
present it manifests no differently than with one. |
|
The Champagne gene lightens the body color and the skin
and eye color. Champagne foals are born with pink skin and blue
eyes; the pink skin color usually deepens and always develops freckles,
and the eye color turns to amber or light brown. |
|
| Silver (dapple)
|
The Silver gene is abbreviated "Z" in genetic
symbols. The gene for absence of Silver is abbreviated
"z". |
|
The Silver gene is a SIMPLE DOMINANT gene. This
means that if one gene is present it will manifest fully, and if two are
present it manifests no differently than with one. |
|
The Silver gene ONLY AFFECTS BLACK PIGMENT |
|
The Silver gene dilutes the mane & tail on a horse
with black pigment to a flaxen or silvery color. |
|
The Silver gene dilutes the black pigment on the body
to a chocolate-brown shade |
|
|
Flaxen
|
It has been believed until this past year that flaxen is
a simple recessive gene. However, since two flaxen chestnuts do
not always produce a flaxen foal, this cannot be the
case. |
|
At the time of this writing, the mechanism by which flaxen
is inherited is unknown. |
|
Flaxen only affects red pigment in manes and tails. |
