Female (reduced orange) and Male (more orange saddles) Granite morph Gray-banded Kingsnakes (Lampropeltis alterna).

Polygenic is the interactions between certain genes to render a snake atypical, compared to it’s nominate (wild-type) form. And “yes” he’s chinning like he wants to take her out for a mouse and some quiet music.
