I'm going to ignore the concept of evolution in WoTdom for now because that opens a whole new can of worms.  hahaha.  Genetically speaking humans and animals are still made up of the same genetic material with the difference in phenotypes resulting from variance in genetic expression.  So it stands to reason that it'd be fairly simple ("simple") to merge two genomes and come up with a new race.  That really makes sense @carnacarn, thanks for pointing that out!  I was struggling with the concept of TP "creating" something, but as you said, it's more of a "merging" than anything else.  

The Fades!!  That's an excellent point!!  My understanding of them are as genetic offspring of trollocs yet the animal side of their merged genome is completely suppressed and only the human traits are expressed.  So logically, if trollocs are pure blends of human + animal, Fades should be completely human.  However, they clearly are not.  They have powers reminiscent of the Dark One himself - (Aginor's comment of them being "slightly out of phase with reality", the cloaks not billowing in the wind, disappearing in shadow, powers without being able to channel, etc, etc.

The difference between a regular human and the human genome in a Fade has to be attributed to the True Power/Dark One's touch.  However, what are the genetics of that?  I've read some people explain it as they inherit the channeling gene, but I'm not quite on board with that theory, as they don't use the One Power.  Second, they are always male.  So either something is special about the male sex-linked traits that allow Fades to come into being OR the female genome is incompatible with life and the fetuses miscarry/die shortly after birth.

Following the logical progression of questions here, if Fades are representations of throwbacks to the human stock, what about throwbacks to the pure animal stock??  I don't recall ever hearing about such creatures, but it would be interesting to know if these "pure animals" have special abilities which differentiates them from the original, regular animals AND if they are only ever female.  

((Edit: I wizened up and consulted the google and remembered the animal throwbacks are stillborn.  Dang.  LOL.))

If the TP is involved, given its nasty little habit of shredding anything and everything it touches, it seems counterintuitive to use it to create a new race.  Unless by usage of that "new race" comes about by removing features from current races.  Not sure if that makes sense.  Haha.  

True Power!  Even better!  There has to be something extra special to DNA rearranging when the DO gets in on the game.

I know the concept of genetics in WoT abilities has come around (and around and around....) many times before.  Example: http://www.dragonmount.com/forums/topic/34770-the-genetic-theory-of-channeling/

But it's been a goodly number of years since it was rehashed, and there are new concepts to discuss, such as proteomics,  transcriptomics, and psychogenomics (the latter of which I could see evolving into a study of the soul, or manifestation of innate behavior, emotion, and personality).  Not to mention the genetics of other things WoTdom.

In regards to channeling, the consensus seems to agree that the learners & sparkers are sex-linked traits due to gender being the basis for the connection to saidar vs saidin. As brought up before, there are some merits to channeling being a sex-linked trait.  If anything, I would suggest that the sparker and learner gene is elsewhere than a sex chromosome (see the Aran'gar argument) and the half of the source the individual touches is determined by sex-linked gene control of promotor regions of the "channeling gene" which induces transcription/translation of one of two isoforms (the result being able to sense saidin vs saidar).  But that's the either/or theory, and still doesn't quite explain a female being able to sense saidin or vice versa.

But what about the genetics of other WoT abilities?  Min?  Perrin?  

What about the shadowspawn created in the War of Power?  Aginor used techniques of genetic engineering to construct animal/human hyrbids.  But he used the One Power to do so.  MIND BLOWING!  What's the science of rearranging a genome with the One Power???? How do you explain that?  (I'm totally not picturing him standing over a plate of stem cells forcing homologous recombination, inducing strand breaks and NHEJ - hahaha).

Anyways, thoughts??? 

Working on my e-book version of Way of Kings by Sanderson.  Which I tend to only read while traveling, so it's a work in progress.  And at the moment am thoroughly enjoying Redshirts by John Scalzi.
