I do not like the idea of genetic analysis tied to social order. Technology review  has an article that details a new type of test that can determine how intelligent someone is by testing their DNA. This has a huge potential for abuse. (seriously, watch Gattaca) 23andMe and Ancestry have already shown that once they have DNA on file, they share it and analyze it like they own it. Be aware of the contract details if you willingly plan on sharing your DNA with any company.
