The Science Behind 23andMe
23andMe's genetic testing relies on advanced genotyping technology. Genotyping analyzes specific variations in your DNA sequence, known as single nucleotide polymorphisms (SNPs). These SNPs act as genetic markers, providing valuable information about your ancestry, health, and traits.
23andMe's database, one of the largest in the world, compares your SNP profile to millions of others, identifying shared ancestry, genetic similarities, and potential health risks based on extensive research and scientific studies.
