In a follow-up to my previous post 10 ways to use your DNA, here are 9 more uses:

11. Artwork. DNA Art Forms, dna11 and DNA-Artistry all isolate your DNA from a swab-sample and subsequently chop it up to create a pattern that is unique to you (similar to the old way of determining human identity). The product is a piece of art to put on your wall. You can see examples here and here.

12. Testing for predisposition to psychiatric disorders. Three companies offer this service, NeuroMark, Psynomics and SureGene. These tests should however, under no circumstance be confused with proper diagnostic tests, as stressed in this article.

13. Genetically customized flowers. Blue roses to replace the now outdated red ones.

14. Test your athletic abilities. Although most of us are probably painfully aware of our limitations already.

15. Glow in the dark goldfish.

16. Genetally optimized SPA-treatment. This however, looks like they have just renamed a nutrigenetics test. Note that nutrigenetic testing has been heavily criticised by authorities.

17. Surname testing which is basically a tool for genealogists.

18. Another such tool is Common birthplace testing.

19. And finally we have the appalling misuse of DNA offered here. This service has rightfully been deemed nonsens….

More uses to follow in what seems to develop into a collection of DNA-use posts.
