From For Utah Billionaire, Search for Roots Is Blooming Field:
A Sorenson company called Relative Genetics Inc. is selling tests for $50 and up that help people figure out where they fit in the database — and sometimes connect with specific ancestors who lived hundreds of years ago.New technology is setting off a genealogy gold rush inconceivable in an earlier era when people had to rely on old courthouse records and half-remembered family lore. Scientists now have several ways of using DNA to determine ancestry. The simplest involves the Y chromosome, which is found only in men and accumulates small changes over the centuries. If men have nearly identical Y chromosomes, it means they share a recent ancestor going up the male line. Another method uses mitochondrial DNA, which passes from a mother to her children. It can be used to determine ancestry through the female line.
Such tests used to cost thousands of dollars apiece. Now they’re relatively cheap — and some entrepreneurs see both scientific and commercial potential. This month, the National Geographic Society announced it was teaming up with International Business Machines Corp. and Family Tree DNA of Houston to build a database of 100,000 samples from ethnic groups around the world. National Geographic is selling a service — for $99.95 plus shipping and handling — in which people can send in their own DNA and find out where they fit on humanity’s family tree. For example, it might show that a person’s ancestors on the male line came out of Africa, through Central Asia and into a particular part of Europe.
I have to think there will be a few unpleasant discoveries when people trace their paternal lineage.
