I don't know about the Malmute but the Wolf maintaining a prick ear is due to the necessity of higher fight or flight response necessary for a higher percentage survival rate. That is actually determined as an embryo when the adrenal gland is forming, and is formed by a group of stem cells called neural crest cells, a higher or lower concentration of these cells at different locations has an effect causing different presentations of the body parts, color or lack of, and disposition. Seems to me that may be how the "genetic mutations" occur. The different degrees of flop or prick ears in dogs is determined the same way and has to do with the amount of the "stem cell" that attaches at those points, which "per breed or specie" becomes a pretty much consistent inheritable trait.
This "theory" began with in Darwins studies and more recently was further studied by a team of researchers headed by an Adam Wilkins and was published in some high falautin Genetics Journal.
