I define those terms as follows:
Paradox: is an abnormal unexpected coloration of the snake based on known genetics. It is usually just a blotch or two or some unexpected colors showing up on usually small portions of the snake. It is not genetic and can't be passed along to the offspring, it's just a random oddity. Here's an example, this should be just a Coral Glow but the black spots can't be explained with normal genetics so we call them a 'Paradox', not genetic so we can't give them a name and can't be passed to offspring. If it were genetic we would give a name to this new morph.
Dinker: is a normal ball python that we think may have potential to have a new color or pattern that is genetic. It may or may not be the next new morph. Most dinkers are just normals with interesting patterns or colors that can not be passed along to the offspring, but we hope they can (everyone hopes their normal is a dinker LOL).
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.
