Good Point Barnes! I'd say if the genetics are somewhere in the gene pool they will come up at some point. If they are no where to be found they will be quite rare. I think before last year we didn't have any split brow tines bucks in the last four years. There was a spot I hunted in Michigan that for three years if the buck has an 8 point rack (which was actually pretty rare) it had split brow tines. You just never know.
