I just learned that Jack Quaid is the son of Dennis Quaid and Meg Ryan. Even if he was born from both alpha parents, he looks completely average beta who can't play alpha leading roles like his parents used to do. This is quite implausible according to genetics evolution rule, where children are usually genetically better than their parents. My theory is that there is something that makes parent's DNA devolve in children instead of evolving.
