HorseLover, the silver gene generally doesn't create a "silver" appearance. Silver Dapple
is the name of the gene, and the name of the color of this gene on a black horse. It's effect on black horses would result in that mottled greyish/chocolate color with the "flaxen" mane and tail (with dark roots). Silver Bay
, is the Silver Dapple gene on a Bay horse. If you think of the way a Bay looks, then combine it with how the silver dapple effects black, you'll get the idea. Silver bay has the regular red body, but the black legs are faded to that greyish/chocolatey color, and the black mane and tail are faded to the "flaxen" color (with dark roots).
This link shows pics of Silver Dapple, and Silver Bay: http://www.mustangs4us.com/Horse%20C...er_dapples.htm
(The horse in the middle of the top is silver bay, the other two are silver dapple.) Silver Buckskin
, is Silver Dapple on a Buckskin. Same cream body, but the legs are that greyish/chocolatey color, and the mane and tail are faded to that "flaxen" color (with dark roots). Grulla/Grullo
is the effect of Dun on a black horse. Many paople use the term "Silver Grullo" to describe the shade of the body, when they do not have the silver gene. Hence the confusion.
Best chances of getting Grullo is a Grullo to Grullo
, second best, Black to Grullo
There is a rare possibility of Silver Dapple occuring on Grullo, making a true Silver Grullo, but this horse would be very odd indeed, and look much like a Silver Dapple, with the dun factoring being just a hint darker. It would still have the "flaxen" mane and tail (with dark roots).
(About halfway down the page on the above link is "Tinkerbelle" a silver dapple dun, aka a true 'silver' grullo.)
Does any of that make sense?
