Are there any genes that do NOT halve over succesive human generations? Sort of an uber-dominant gene?
Note: I asked this question in the science section so that it would get noticed by those who actually know lots about genetics, not how to write a story, which is what the answer to this question will be used for. I plan to use this idea for a fantasy series. It will be a gene that makes it so that the ruling class have a stronger potential for magical ability and prowess then the average citizen. Not that I mean to constrain fantasy to an entirely realistic premise, of course. It just helps to have a basically logical premise for a story, given that a magical realm works differently than ours.
