Over the next decade, we will have the opportunity to learn about all kinds of predispositions and proclivities buried in our DNA, from health risks to behavioral tendencies to traits affecting abilities such as intelligence, athleticism, and musical talent.

In recent weeks, two companies (Instant Chemistry and Singld Out) have made a media splash with their launch of a new direct-to-consumer genetic testing service to help determine compatibility in intimate relationships.
