About the Ancestry Service

23andMe® brings the world of genetics to you. 23andMe analyzes variations at specific positions in your genome. These variations, called SNPs (Single Nucleotide Polymorphisms), has the potential to tell you about your ancestry.

The 23andMe Ancestry Service includes:

Customers who purchase the Ancestry Service will be able to add all of the existing Carrier Status*, Genetic Health Risk*, Wellness and Traits reports later for an additional fee.


Ancestry Composition Report

This report uses DNA you inherited from recent ancestors on both sides of your family and tells you the proportion of your DNA that comes from each of 31 worldwide populations, offering a detailed view of your ancestry.

The Ancestry Composition results reflect where your ancestors may have lived before ocean-crossing ships and airplanes came on the scene.



Haplogroup Reports

These reports tell you about the ancient origins of your matrilineal and patrilineal ancestors. Haplogroups are assigned by finding the genetic variants that are unique to each group. These genetic variants typically originated tens of thousands of years ago. Women and men both receive Maternal Haplogroup report based on their mitochondrial DNA; men also receive a Paternal Haplogroup report based on their Y chromosomes.


Note: Your matrilineal ancestors include your mother, her mother, her mother's mother, etc., and your patrilineal ancestors include your father, his father, his father's father, etc.


Neanderthal Ancestry Report

Even though Neanderthals vanished about 40,000 years ago, their DNA lives on in us. Based on research, Neanderthals interbred with humans around 60,000 years ago. Our Neanderthal Ancestry feature will tell you how much of your ancestry can be traced back to Neanderthals using SNPs located across all of your autosomes and your X chromosome(s).



Your DNA Family

The 23andMe Your DNA Family report tells you about the diverse group of 23andMe customers who have DNA in common with you and how many of these DNA Relatives you have around the world. After viewing this report, you can connect with your genetic relatives in the DNA Relatives tool.



DNA Relatives Tool

The 23andMe DNA Relatives tool requires customers to opt-in to the feature to access it. This is a popular, interactive tool that allows you to find and connect with genetic relatives and see specific DNA segments you share with them. The DNA Relatives tool can identify relatives on any branch of your recent family tree by taking advantage of the autosomal chromosomes—the 22 chromosomes that are passed down from your ancestors on both sides of your family—and the X chromosome.



Additional Tools and Features

The Ancestry Service also includes:

  • Access to your raw, uninterpreted genetic data file** (Must not be used for medical or diagnostic purposes). Learn more.
  • Access to share, compare and discover more with friends and family. Allowing you to trace DNA through your close family and explore the genetic similarities and differences between you and family members.



*The 23andMe PGS test uses qualitative genotyping to detect clinically relevant variants in the genomic DNA of adults from saliva collected using an FDA-cleared collection device (Oragene·DX model OGD-500.001) for the purpose of reporting and interpreting genetic health risks and reporting carrier status. It is not intended to diagnose any disease. The relevance of each report varies based on ethnicity. Each genetic health risk report describes if a person has variants associated with a higher risk of developing a disease, but does not describe a person’s overall risk of developing the disease. These reports are not intended to tell you anything about your current state of health, or to be used to make medical decisions, including whether or not you should take a medication or how much of a medication you should take. Our carrier status reports can be used to determine carrier status, but cannot determine if you have two copies of any genetic variant. These carrier reports are not intended to tell you anything about your risk for developing a disease in the future or anything about the health of your fetus, or your newborn child's risk of developing a particular disease later in life. For Gaucher Disease Type 1, we provide a single report that includes information on both carrier status and genetic health risk.

**This data has undergone a general quality review however only a subset of markers have been individually validated for accuracy. The data from 23andMe's Browse Raw Data feature is suitable only for research, educational, and informational use and not for medical, diagnostic or other use.
