mtDNA and nuDNA
Contrary to mtDNA profile testing, nuDNA profile testing for ancestry research or crime investigations, is comparable to a ‘fingerprint’, thus a 100% correct identification parameter.
The mtDNA (mitochondrial DNA) genome has only 16,569 base pairs and is much more tightly packed, than the 3+ billion pairs in the nuDNA (nucleus DNA) genome.
Mutations can steadily accumulate in the 98%-nuDNA part, because they seldom impact bodily functions severely, and are often passed on to succeeding generations.
The ancient mystery schools taught that because of the above, the 98% part of the nuDNA molecule functions only at about 30% efficiency.
From a pure biological perspective, the mtDNA functions at a very high level of efficiency. A mutation will probably cause death, and thus not be passed to subsequent generations. This makes the DNA in mitochondria extremely highly conserved, which means it changes very little over time.
No more than 120 of the 16,569 base pairs vary between all humans who lived during the past 400,000 years. Neanderthals carry 200 variants. Chimps 1500. All of them are found in the 2% of mtDNA that is not vital to our lives.
A gene called FOXP2 is of overwhelming importance to any creature, because it controls a “downstream” cascade of genetic processes in hundreds of other genes, who together coordinate the formation of various parts of a body as it gestates and grows to maturity.. See illustration below:
Because it is so utterly vital, it is even more highly conserved than mtDNA. Every normal human has the exact same array of 2,594 base pairs in its FOXP2 gene!! ZERO variations!!
However, mutations have been found. Most had a severe impact or caused termination of life. Sofar, none have been passed on to next generation humans. Therefore, in almost all humans, the FOXP2 master gene is absolutely identical.
