Hi ShowMe,
So that means it can't be used to determine a match? What about Midocondrial {sp} DNA. Can degraded DNA be used in that test?
Scandi
Scandi, the "DNA" does not even have a full set of markers. For the DNA to be considered complete and viable, it has to have (at the very least) 13 markers.
The DNA in question was found mixed in a tiny drop of blood found in JBR's underwear. From what has been documented, the DNA has perhaps 9 markers, and maybe half of 10.
That is why it is said to be "old," degraded and not related to the crime. Complete DNA can be extracted from 1,000 year old mummies and fossils. It does not degrade (and lose markers) easily.
Obvously, a complete set of JonBenet's 13 DNA markers was found in the small spot of blood, as well as an additional 9 markers. Where did those extra 9 markers come from, and why are they not complete? If they were deposited at the same time (within the same 24 hours) as JBR's blood, there should be a full set of DNA markers.
This is the primary argument against the DNA being that of some nefarious intruder. In addition, the underwear was apparently new from a package and never washed. This leads LE to wonder if the partial DNA was in the underwear BEFORE it ever touched JonBenet.
Mitochondrial DNA can only be traced through the female line. Burke and JonBenet would have Patsy's mitochondrial DNA, and their maternal grandmother Nedra's MtDNA, and further on back. However, Burke cannot pass on this MtDNA to his children ... it is only passed on by the female.
This presents an interesting sidenote to the assertion that the partial DNA is not that of a "Ramsey male."
If the partial DNA is viewed from the standpoint of MtDNA, that excludes John Ramsey and his son John Andrew Ramsey (who was not a child of Patsy Ramsey). However, it DOES NOT exclude Burke Ramsey. Mitochondrially speaking, Burke is not a "Ramsey" but belongs to the maternal side of Patsy's family.
I am not saying Burke is the source of the partial DNA, I am just pointing out the "word games" sometimes used by lawyers and LE when they try to influence public opinion, or do not wish to make full disclosure of evidence.
IMO
