Finally... research gives the answer:
According to genetic research forums elsewhere and supported with pics for pibald recessive traits in reptiles...
When the lineage of both parent bloodlines are genetically pure enough for the traits for color, the recessive trait can cause "markers" to appear on the young. The markers usually manifest as areas of the recessive color appearing without the recessive pattern, or pattern "interference" which may cause neither parent pattern to be presented and look quite abnormal (not physical form... just the patterns).
or a combination of both.
These fry are 100% heterozygous BGJD with markers indicating they carry the electric blue recessive trait.
As noted elsewhere in forums on MFK... Some people have said others had told them they can tell BGJD from normal wild type but stated that they themselves couldn't, nor did they know of anyone who had sucessfully demonstrated this for them... evidently they presented BGJD w/o markers for discernment in which case it supported the flawed conclusion.
The answer is simple and rare... BGJD with markers can be distinguished from wild type and BGJD w/o markers. The advantage? Simple... If these are bred to each other, the result is 25% strong or exceptionally colored electric blue... 25% wild type of same high color quality of the wild type source... and 50% heterozygous electric blue recessive gene carriers (with markers)!
No more trial and error breeding thier young time and again to figure out which ones carry the gene.
I still do not recommend inbreeding, no matter how strong the color traits. This practice is what lead to all the blatant deformities rampant throughout the EBJD presented at LFS as cheaper and sadly, greatly inferior.
