. . . to know for sure if it has bloodred in it is in breeding trials. I have hatched many snakes that color blend and have never been in the bloodred family tree. The belly can sometimes "hint" of bloodred origins, but not the markings or colors. What you have there is an excellent looking hypomelanistic corn. The super hypos tend to be more yellow. You can see what I mean if you take your picture into an image editing program and reduce the black. The result is either a lighter red than that or yellow. More of a straw color.
Having judged it that way, I will say that no two families of hypos are the same. I've seen 100 or more different shades of red or orange or yellow in hypo corns.
Nice snake.
