This discussion does not seem to adress the question of whether enchi and cinnamon might be linked. Two genes are linked if the two loci are close together in the same chromosome. With over 200 mutants known but only 18 pairs of chromosomes, it seems likely that there ought to be some linkages. Ball pythons have a relatively small number of eggs, and there would have to be controls for parthenogenesis and retained sperm, so results from a few clutches may not be enough to prove anything.

As far as I know, pastel and spider mutant genes are not linked. When a pastel spider ball python is bred to a normal, 25% of the babies are expected to be normal. And 25% of the babies are expected to be both pastel and spider. If two mutant genes are closely linked, possibly as few as 1% of the babies would be normal, and 1% would be crossovers. And if we control for parthenogenesis and the normal parent is female, we'd have to delete the normal babies from consideration.
