Informations générales
The G-locus or grey gene causes progressive loss of pigment (fading) of the hair and is considered to be the “strongest” of all coat colour modifying genes. The decrease of pigmentation may occur over time, leading to the disappearence of the original colour.
Caractéristiques cliniques
A horse that inherits a Grey/Gray coat colour can be born in any colour. Often those horses become completely white by the age of 6-8 years, others will keep tiny non-faded spots (also called fleabites).
Additional Information
The dominant allele G results in the Grey/Gray coat colour and the recessive allele N does not have an effect on the basic colour. The dominant allele G has a duplication of a part of the DNA. The test does not discriminate between horses carrying 1 or 2 copies of the duplication (N/G or G/G). All horses carrying the duplication will turn grey.
Specific breeds are undefined.
