On another forum I use there is a current debate on the silver dapple gene being expressed in the Arabian breed. They are suggesting that the silver dapple gene in Arabians shows as a plum coloured chestnut with lighter mane and tail. As far as I am aware this does not appear to be what I would class as 'true' silver dapple colouration as found in Icelandics, Shetlands, Highlands and Rocky Mountain Ponies. Chev, do you have any theories or opinions on this colouration in Arabs? I thought you needed the horse to be genetically black to allow the expression of the silver dapple locus? The true black Arab is of course exceedingly rare. But you could write my knowledge of genetics on the back of a postage stamp.
