Now pretend that pastel occurs because the pastel has a mutation that decreases the amount of melanin produced. ... I just don't see how that pastel mutation (less melanin) is going to help make up for the improper NC cell/melanocyte migration mutation. (All of this is just speculation of course -- I have no idea what's going on on a molecular level to cause the spider phenotype -- but my point is that I have a hard time seeing a molecular reason that other mutations could "fix" the spider wobble.)
Because lets say the expressed spider gene causes a gap in the allele that is responsible for proper motor function. It is possible that since another mutation has the complete allele that it could fill the missing gap and in turn restore proper motor function. It's 100 percent possible that the gene that causes the spider mutation also causes other physiological like vertigo that can be corrected by additional gene's..It's done in other life forms all the time; I.E. Cows, vegetables, horses, people gene replacement or supplement therapy is a possible solution's to debilitating genetic disorders.
