genomes and counting!

DNA.Land has been designated by Family Tree Magazine as one of the three Best Genetic Genealogy Websites of 2016.

Know your genome



We will compare your DNA with reference data from different populations to see where in the world your ancestors might have lived


Fill in the gaps: convert your genome into a more complete sequence. DNA is inherited in chunks, which allows us to infer sites that occur on the same chunk even though they have not actually been sequenced


Connect with distant relatives who share stretches of DNA and fill in some branches on your family tree

The DNA Land Community


Help science

  • By sharing your data you are enabling scientists to make new discoveries
  • We also want to enable you to learn more about your DNA!

not for profit

  • Participation is free
  • DNA Land is non-profit and run by academics affiliated with Columbia University and the NY Genome Center


  • We value your contribution to scientific research
  • DNA Land members fully consent in order to join

DNA.Land is in partnership with the National Breast Cancer Coalition (NBCC) to better understand the genetic risks of breast cancer. NBCC has focused on gaining access to quality, evidence-based care for all, increasing the influence of breast cancer patients and activists in the decision making that impacts all issues surrounding breast cancer, and on research to end breast cancer.

Frequently asked questions

DNA Land is a place where you can learn more about your genome while enabling scientists to make new genetic discoveries for the benefit of humanity. Our goal is to help members to interpret their data and to enable their contribution to research.
To help understand the genetic basis of different traits, we will ask you to fill out surveys relating to your (or your family’s) ancestry and health.
We will not share with third parties or make public without your explicit permission: the personal identifiers in your profile, your contact information, your individual-level survey results, or your individual level genomic data. We will only share with other researchers or publish aggregated data as detailed in the consent.
After registration, we will ask you to download your genome data directly from the DNA testing website. Currently, we only support 23andMe, FamilyTree DNA, or If you don't know how to download your data, don't worry! We will provide you with step-by-step instructions. Then, you can just follow the registration and upload process. Importantly, your data won't be collected until you complete the consent as part of the registration process.
You must have access to your genome data in order to participate in DNA.Land.
No. We are geneticists from Columbia University and the New York Genome Center who work independently of these companies. We do not advise them or have any financial or business connection with them.
Before you can join DNA Land, it is important that you understand what research is being done and that your participation is entirely voluntary. For your reference, you can view or download a copy of the consent document.
By being part of DNA Land, you will be able to connect with the scientific community and learn more about your genome for free, including information about ancestry and relatedness to other individuals on the site.
When you register for DNA.Land, you will have the option find relatives based on genetic matches. You can learn more here.
Your contribution badge represents your total contribution to scientific studies. DNA.Land awards points for every question you answer and the badge shows your total accumulation. The badge also highlights how your contribution compares to all participants on the website using a percentile score.
