Then they powdered single teeth from 36 skeletons ranging in age from 3300 years to 1500 years old and extracted tiny fragments of mitochondrial DNA (mtDNA), a marker commonly used for genetic typing of human populations. (sciencemag.org)
CEPH's idea was to develop a reference panel of large families, taking blood samples from each of their members to build up a cell bank for genetic typing. (newscientist.com)
