Hm.. I guess my argument is that deafness is an inherited trait from the parents (i.e. it's a gene carried by one/both parents that becomes a dominant trait in the foal that is deaf) and therefore is a pedigree problem, i.e. through genes.
You could look at it this way:
NOT ALL bald faced horses are deaf, therefore when you get a bald faced horse, you are NOT guaranteed that it's deaf. IF 100% of bald faced (patterned) horses were deaf, then I would agree that it's a pattern problem.
HOWEVER, since not ALL bald faced horses are deaf, that leads me to believe that it is a genetic problem, NOT a color problem.
I believe it is the close proximity of the colour gene loci is relation to one of the deafness mutation genes, which would make some people think that it's color-related, but it's not, it's just color ASSOCIATED. *
Does that make sense?
(Think of it this way.... not all white cats are deaf... but some are. White =/= deaf; the gene = deaf, it just so happens that the color is associated with it.)
