Didn't know this kind of tests could be brought home... interesting. Can you build manual relationships with other DNA results from people you know?
It would be crazy to assemble such research data, but at the same time very powerful. I mean... imagine all family members now either start doing DNA tests or automaticaly having DNA information when doing analysis and linking their decendents or relationships... this means these systems would have additional data and could potententially estimate more relational databases/information.
For sure an huge expeirment with very low sucess due the privacy implications this has. Definitively, still something to think about.
