Do you prefer to run marathons or the 100-yard dash? Do you rise at the crack of dawn or sleep until noon? Genetics may lie behind your answers to these questions. 23andMe helps you explore the genes underlying your personal characteristics. You can also link to participating family members and friends and see whether you share any genetic similarities.

23andMe's Genome Explorer displays more than a half-million data points in your genome in a form that you can visualize and understand. You can browse your chromosomes, or zero in on a particular gene by typing its name into the search box. For example, if you read that scientists have discovered an association between a particular gene and some physical trait or condition, you can use the Genome Explorer to find out what the news might mean for you.
