WT - Good question. I based my first answer on Wonder Woman’s daughter as portrayed in Frank Miller’s generally dreadful Dark Knight 2. Should have given it more thought and research. According to DC cannon the Amazons were created by the goddess Aphrodite, and are both immortal and eternally youthful. Whether or not they could reproduce naturally is an open question, as they don’t really need to. Wonder Woman’s side-kick Wonder Girl was an orphaned girl, rescued from a fire by Wonder Woman and given Amazon powers by a mysterious purple ray.

Having passed through my comic-reading years sometime in the 80s — before, apparently, the superhero baby boom — I was unaware of the super-progeny mentioned above…

I am surprised, however, to learn that Dr. Banner and Peter Parker were able to pass their abilities on to their offspring, as their powers were derived from exposure to gamma radiation and radioactive vermin, respectively…

Do Marvel and DC imply that gamete DNA is affected in a manner that is consistent with somatic DNA?

Or could it be that the male gametes are formed using the post-superpower-onset DNA, which would contain superpowerful DNA that could be passed along to offspring — at least by males?

Unfortunately, I suppose, this would not be possible for female superheros who get their powers from an external influence, as their ova would have been formed in advance of the superpower-causing incident……..
