Very loose and mostly peri-scientific blogs, such as Panda's thumb http://www.pandasthumb.org/archives/2007/06/junk_dna_junk_s.html are on record now to measure our understanding of the function of the whole genome by the ability to "pass the onion test", best formulated by Ryan Gregory (essentially the same as Richard Dawkins' "Salamander paradox"; that different sub-species of Salamandra have a great diversity in their size of "junk DNA").

Note that the fractal nature of a part of a fractal image can de determined by examination of both the smaller details and the larger details. This is not the case with barcodes, where the smaller details of the sequence do not reflect exactly the organization of the whole genome. It is like saying that tossing a coin a few times is representative of many tosses. One cannot predict the long frequency data from a particular coin from only a few tosses. One needs sufficient data to do a chi-square test. Same with barcode data. I’m not sure this applies.
