23andMe provides personalized genetic reports by analyzing your DNA from a saliva sample.
How 23andMe Works
23andMe uses a process called genotyping to analyze your DNA. This involves looking at specific locations in your genome, which are known to vary between individuals. The results are then used to generate detailed reports.
Types of Information Provided
23andMe's analysis leads to a variety of reports, including:
- Ancestry Composition: This reveals your ethnic and geographical origins.
- Traits: This covers genetic predispositions to various physical and behavioral characteristics.
- Genetic Health Risks: This identifies potential increased risk for certain diseases or conditions.
Example of Reported Traits
- Whether you are more likely to have straight or curly hair
- If you have a preference for salty or sweet foods
- Your likelihood of being lactose intolerant
Example of Reported Health Risks
- An increased likelihood of developing type 2 diabetes
- A predisposition to certain types of cancer
- If you are a carrier for specific genetic diseases
Summary
Essentially, 23andMe provides an overview of your genetic profile, encompassing your heritage, predispositions, and potential health concerns. This information is derived from specific genetic markers that are analyzed from your saliva sample.
