The minimum requirements of Sabino must still be met regardless if Silvertail is shown or not.
Silvertail is not listed in the phenotype, a Sabino with Silvertail is still only written as Sabino.
Even if sabino markings are minimal or barely visible at all, the tail can be fully or partially white.
A partial expression appears as a soft gradient where the bottom of the tail is white or much lighter than the base of the tail. A full expression makes the tail completely white.
Affects eye colour the same way sabino does.
Affects skin colour the same way sabino does.
Affects horn and hoof colour the same way sabino does.
