[Superman] If Jonathan Kent II is only half-Kryptonian, then shouldn't he only be half as powerful as Clark?

I'm just thinking from a genetics POV.  Like, when a dark-skinned person marries and has babies with a light-skinned person, the resulting kid typically is lighter than the former, and darker than the latter.  

In the same way, Jonathan should be stronger than Lois, but weaker than Clark, due to his human genes.

That's not how genetics work. You have dominant and recessive genes, so the expressed phenotype is one of the other, not a combination of both. Where it gets tricky is that traits are usually a combination of genes, so it's pot-luck what you get. 

It's possible that kyptonian genes are dominant over every corresponding human genes. So while Jonathan's genome is a 50/50 mix of kryptonian and human, his phenome expresses 100% kyptonian.
