Coat colour genes
Genetic disorder tests
Horses and ponies that carry the gene variant that causes greying with age are special. They go through a beautiful range of shades on their way to becoming completely white or flea-bitten grey, but they also have a high risk of developing melanoma.
Genetic testing can confirm whether your horse has the gene variant that causes greying with age and increases susceptibility to melanoma.
