Chimera: is a genetic anomaly, i.e. more than the usual number of genes in one genetic locality. We know we need two genes at one location for a recessive or a super, a Chimera has three or more at that location and it's a one time oddity that can't be reproduced.
While Paradox and Dinker have completly subjective definition in the hobby, chimera is pretty established in biology already and that's not how it works. Chimeras have 2 (or more in theory) sets of DNA. Essentially siblings in one snake.
