The psychic is, quite literally, the new kid on the block as far a psychics go; his name is Tyler Henry, and apparently the basic cable channel E! is really pushing a TV series featuring him, Hollywood Medium With Tyler Henry. His website describes him thusly:
Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants, in the chloroplast. In humans, the 16,600 base pairs of mitochondrial DNA encode for only 37 genes.
Results are returned for all three regions of the mitochondrial DNA: HVR1, HVR2, and an area referred to as the coding region (00577-16023). A perfect match indicates a common ancestor in recent times, making it the only mtDNA test very practical for genealogical purposes.tDNA testing is generally done in two regions of the genome known as hyper-variable regions: HVR1 (16024-16569) and HVR2 (00001-00576). Testing only HVR1 will produce low resolution results with a huge number of matches, so most experts generally recommend testing both HVR1 and HVR2 for more precise results.
