Debbie, thank you so much for the great article. So Sukie, is leucism just a broad umbrella term for any neurocrest disorder that results in any type of hypopigmentation? I know it says it's the name of a "phenotype", but I can't keep these terms straight and I don't know what that is. Phenotype is what, like the appearance of an organism? Why not just say neurocrest disorder or if you are wanting to label the appearance say "blaze", "piebald", etc? I suppose it's just a broad term to describe lightening in coloration rather than a reference to the genetic condition? Or do I have it all wrong and is this just a fancy way of describing "white" and has nothing to do with a neurocrest genetic defect? -- waiting in the corner with a dunce hat on for your input Leucism would describe our BEW's and/or DEW's ... or would it? I see differences between dark garnet colored and blue eyed DEW's and BEW's with jet black eyes as a whole. I always assumed that the DEWS have a neurocrest defect because so many of them are deaf. Again, it was a really fun thing to read Debbie, thanks so much. Wolfy ps, if people would like to read how these things relate to ferrets as a species and how some ferrets may appear who are affected by neural crest defects, see www.wolfysluv.com/deaf.html . There is also a more in depth article located on the SmallAnimalChannel.com site. I'd supply the url, but the site seems to be having a hard time loading for me right now. Google Living With Deaf Ferrets and it'll pop right up. [Posted in FML 7095]
