The GENOGRAPHIC project, organized as a research partnership of National Geographic and IBM, proposes to explore the migratory history of man by analysing mutation patterns in mitichondrial DNA and the Y chromosome. The focus will be on indigenous populations, but individuals from the general public are invited to participate by anonymously submitting two samples of DNA (buccal swabs) and a fee of $100. Some of us are torn between interest in the project and concern that this vast collection of diverse genetic material may be used in other applications (for instance, the establishment of a genetic research bank using the spare second sample...). Any insights, advice, reassurances or caveats from someone more fully acquainted with this would be much appreciated.
