DNA challenges

Fun, scientifically responsible challenges against your own raw data file — all run locally in the browser. Genetics suggests; it does not decide. Challenge a friend to check their own file!

Pick a challenge

• The coffee DNA test — 6 questions about your caffeine habits give your coffee type; share it and challenge a friend. No file needed.
• The coffee DNA challenge — are you a fast or slow caffeine metabolizer? CYP1A2, rs762551.
• The bitter taste challenge — can you taste PTC bitterness? TAS2R38, rs713598.
• Night owl or early bird? — what does your chronotype genetics suggest? CLOCK, rs1801260.

How the challenges work

• You need your raw data file (23andMe, MyHeritage, AncestryDNA or FTDNA) — download it here.
• Check the marker for free via the rsID lookup or analyze the whole file locally in the app.
• Everything is educational: associations in research data, not medical statements.
