Phylogeny of modern humans in Europe:
about how close relatives we are.
Matrilineal inheritance of mitochondrial DNA
When combining genetic material forming a descendant, extrachromosomal DNA located in the parents mitochondria are not combined. The sperm's mittochondria do not enter the egg cell and if ever one gets through, it's eradicated. Therefore only the mother's extrachromosomal DNA is passed to the next generation.

Genetic Testing - the basic idea
As mitochondria are passed along the matrilineal path of heritage, mitochondrial DNA contains the memory of human ancestry. A close look at specific regons gives insight into this mystery. Most analysis is based on the d-loop region, where selection on mutations is lesser than in coding regions. This implies DNA-sequencing, which is not within reach to us.

Genetics Testing by AFLP for Clade Ursula
Based on the findings, that there are specific REnzyme cutting sites present or absent defining membership to a specific clade ( see "Genetic testing - the idea")
subsequent PCR-reactions for the most abundant clades were performed.
For the Clade U we amplified the mitochondrial DNA from
pos. 12104 to 12338, yielding a PCR-product of 240 nucs.
