I don't know much of where Connor's Luthor connection went in the comics, so I am curious to see where the show is going with that.
Originally, it was revealed that Cadmus Director Westfield served as the human DNA for Superboy. Later, while President, Luthor started anonymously dropping hints that, in fact, it was his DNA that was blended with what they could figure out of Superman's to create him.
Superboy struggled for about 2 years with the whole "nature versus nurture" thing, until Luthor contacted him and spoke a code word which turned Superboy into a weapon against his friends in the Titans. Superboy, with the help of his friends overcame this and Superboy exiled himself to Kent farm until Superboy-Prime came to "talk" (which ended up with him brawling with Superboy, eventually almost killing him, as well as killing and maiming some Titans in the process).
Superboy recovered, partially, and went to confront Superboy-Prime, this time, dying, but destroying a machine an alternate-Luthor was using to restart the universe in his twisted plan to create a perfect universe.
Superboy was resurrected during the Legion of Three-Worlds mini-series and spent the first part of his resurrection trying to decide if he was more like Luthor than Superman, but ultimately realizing nuture trumps nature.
