| We all know that DNA has the ability to
identify individuals but, because it is inherited, there are also regions of the
DNA strand which can relate an individual to his or her family (immediate and
extended), tribal group and even an entire population. Molecular Genealogy (宗谱学)
can use this unique identification provided by the genetic markers to link
people together into family trees. Pedigrees (家谱) based on such genetic markers
can mean a breakthrough for family trees where information is incomplete or
missing due to adoption, illegitimacy or lack of records. There are many
communities and populations which have lost precious records due to tragic
events such as the fire in the Irish courts during Civil War in 1921 or American
slaves for whom many records were never kept in the first place.
