Different skin tones were results of isolation. What you don't realize is that this is new information as well. Initially the genes did not have the code for the middle Mandarin palette, later they will. See -new info.

A 75% chance, to be exact. If only one parent carries the recessive gene, then there is a 25 % chance that it will be inherited and if it is, the phenotype will not die out.

Probably that's what they used to say about people with blue eyes, which too is a result of a specific mutation.
