I think your getting too hung up on the chimera thing. I really think there are two types of paradoxes: the chimeric paradoxes, wich seem to be the ones that are roughly 50/50. these animals are more extreme, and also never prove inheritable as the reproductive tissues are all that matters in terms of breeding and they can only be from one twin, not both simultansously.
Your animals seem to be the second type, those with a much smaller region of atypical pigmentation. I really think the mosaic monosomy explains this perfectly, it also exlains why your animal breeds as a het and not as an albino, as proven by the one normal offspring.
What I dont know and have not been able to figure out thus far is what happens when you breed an animal that is missing one copy of a gene.
Normally an animal passes one copy of each gene to its offspring, and as each parent has 2 copies of each gene the odds are 50/50 as to which copy of the given gene the offsping will recieve.
What I dont know is in this condition, with an adult possesing only one copy of a given gene and an empty spot where the other copy should be is this: Will all the offspring inherit the one functional copy of that gene, or is it possible that the parent can in fact pass along the empty spot, essentially passing no copy at all 50% of the time. If its possible for an animal with this monosomic condition to pass along the empty spot then its explains why you have produced paradoxes more than once.
This mechanism is entirely different from a chimeric paradox, wich could never be inherited.
