Thank you for the Punnet squares, they illustrated the point even though skin is controlled by multiple genes. You did a good job with the squares, though...I love those things...*clears throat* Anyway I don't think Liir's coloring was ever described, besides to say that it wasn't green. I guess I'm a minority, but I pictued Fiyero (bookwise) as having African skin coloring. Perhaps that's just me.
Another note on the Punnet squares, though...let's use blood types as an example for now; I promise this relates to the topic. A and B blood types are both dominant. If someone gets an A blood gene from one parent and B blood from another, the person gets the hybrid, AB type blood. But if they get an A and an O (the recessive) the person has mixed genes (A and O) but has type A blood because A is the dominant gene. And then, if someone had type A blood and mixed genes (A and O) and someone else has O blood (which needs to be pure O and O because O blood is recessive) their child would have a 50% chance of having A type blood (with the mixed A and O genes) and a 50% chance of having O type blood (with O and O genes).
If the same applied to skin coloration, the only way Liir could have mixed skin coloring is if the lighter (Elphie's) and darker (Fiyero's) skin colors were both dominant. Assuming Elphie and Fiyero had parents of the same race (capital letters are dominant, lowercase are recessive) the square would look like this:
__F__F_
E|EF|EF|
E|EF|EF|
Liir would have the mixed coloring, EF skin.
If Elphie's genetic skin was recessive, however:
_F_F_
f|Ff|Ff|
f|Ff|Ff|
Then Liir would have mixed genes but Fiyero's coloration, because his genes are dominant.
And, finally, if Fiyero was of mixed race:
_F_f_
f|Ff|ff|
f|Ff|ff|
Liir would have a 50% chance of getting Elphie's genetic coloring and a 50% chance of getting Fiyero's coloring. At least, that was how I learned it, you can correct me if I'm wrong. But what Emeraldgreengirl said before rings true; skin color is controlled by several genes. These squares show the results if skin coloring was controlled by one gene only.
In other words, unless someone can map the effect that all of those genes would have on Liir and we could trace the genes of Elphaba and Fiyero (because who knows what those two have inherited from whatever ancestry they have), we have no way of knowing what Liir's skin color is unless Gregory Maguire ever decides to tell us. Aagh!
