Analyses — specific DNA questions

Each page answers one concrete question: what the analysis explores, which variants it builds on, what the result can and cannot mean — and how to start. Your file is always analysed locally in your browser.

  • Height & heredity — An estimate of your genetic height potential based on hundreds of associated variants in your raw DNA file.
  • Caffeine metabolism — Explore the genetic variants associated with how quickly your body breaks down caffeine.
  • Type 2 diabetes & heredity (health­related — educational information) — See which common genetic variants associated with type 2 diabetes are present in your raw file — with clear limits on what the result means.
  • Sleep & chronotype — Explore genetic variants linked to your chronotype and natural sleep duration.
  • Hair loss & heredity — See the genetic variants research has linked to male-pattern hair loss.
  • Eye colour & heredity — Explore the genetic variants steering iris melanin — and your eye colour.
  • Mosquitoes & genetics — Explore genetic variants linked to mosquito attraction and how strong bite reactions tend to get.
  • Freckles & sun sensitivity — Explore genetic variants linked to freckles and how easily skin burns.

DNA analysis runs locally in your browser — your raw DNA file is not uploaded. DNA Chat is optional and off by default; genetic information is sent only after your explicit consent and may then be processed outside the EU/EEA. More about DNA Chat and privacy.
