Thanks for the genetic update on Frank, Lewella! When he was a foal I could have sworn that he had red tips on his ears but that must be another white that I am thinking of...Frank's dam is a black based either gray or blue roan. That is so interesting about the different gene...where can Jill have Wyatt (Best Dressed Man) tested? I have a little sorrel mare in foal to him for next year (an actual sorrel that does not have a silver gene). She has white hairs throughout her coat and has produced nearly all sabino type roans eventhough she is solid. I would be cool if I could get a white filly out of her and Wyatt! Jill did have a white foal out of Wyatt this year. Lovely colt. He went to a lady down here in Texas. His dam was Van-Lo breeding and was a pinto.
I wonder what Blizzard, Snow and Snowflake would have all tested? They were by Rock E's Painted Logo and out of a red roan sabino mare and all three of those were born pure white with black eyes and no pigment whatsoever...even when they were wet. So far all of Wyatt's white foals have had blue eyes (Wyatt does not have blue eyes himself though).
I think that Betsy Bailey has a white mare for sale that she got from Wayne Williams. I have no idea if she is a sabino or if she is a cremello. I have had a silver buckskin stallion from Wayne's breeding program, that did produce two dilutes, both colts. One is here in Texas and the other is either in Maine or Maryland. He has quiet a bit of silver in that Peaceful Acres gene pool. I had a HUGE waiting list wanting the one colt if he would have been a filly so they are definantly not easy to find!
Oh, they are not Shetlands, but Don Chegwidden , Cheg-Kim Ponies in KS, raises several cremello AMHR miniatures each year and for some reason he gets mostly fillies.
