It is mentioned very early on that marriages between high ranking darkeyes and low ranking lighteyes are not unheard of, has the heritability of eye-color ever been addressed in any of the many AMAs Sanderson has done?
In the event of a hypothetical marriage between a lighteyes of the 10th dahn and a darkeyes of the 1st nahn what would the probability be that a child would be lighteyed verses dark, and would the child's social rank depend on phenotypical eye-color?
