Paradox animals are never produced from breeding homoXhomo as all the offfpsring would be homozygous and you wouldnt notice any chimeras.
I have been talking about the chimera thing for years and its the only explanation that fits all cases.
In the case of paradoxes that come from het X normal and the resulting animal appears as either the homozygous form or at least partly expresses the homozygous phenotype there is another explanation.
Monosomy or "mosaic"monosomy would explain animals like the paradox super mojave that was posted.
In this genetic disorder, some of the genetic information from one parent simply fails to transmit to the offspring. The result is that they are missing one copy of certain genes.
If the animal such as the mojave shown simply did not recieve the normal copy of that allele from the normal parent. This leaves only a single copy of that gene and since it was the mojave version , the areas that lack the second normal copy appear luecistic.
People assume that its the presence of the second copy of the mutatn gene that makes the "super" when its far more likely that its really just the ABSENCE of any normal copies that creat the homozygous phenotype.
