Whole Genome Sequencing Explained: Why It Matters for DNA Testing
Learn what Whole Genome Sequencing (WGS) is, how it compares to genotyping DNA tests, and why GenoConnect uses WGS for the most accurate ancestry and health results in India.
Whole Genome Sequencing (WGS) is the gold standard in DNA analysis. While most consumer DNA tests read a tiny fraction of your genome, WGS maps nearly every base pair of your 3-billion-letter genetic code. GenoConnect uses 30x coverage WGS — meaning each position in your genome is read an average of 30 times for high accuracy.
How WGS Differs from Genotyping
Genotyping (used by 23andMe, AncestryDNA, and most Indian competitors) uses a microarray chip with pre-selected SNP markers. It is fast and cheap but limited — it cannot detect structural variants, rare mutations, or novel variants. WGS reads everything, enabling deeper ancestry resolution, rare disease screening, and pharmacogenomic analysis that genotyping cannot provide.
Benefits of WGS for Indian Users
- More accurate South Asian ancestry breakdown due to access to millions of additional variants
- Detection of rare genetic variants relevant to inherited conditions in Indian populations
- Complete pharmacogenomic profiling for safer medication decisions
- Future-proof data — as new genetic associations are discovered, your WGS data can be re-analyzed without retesting
- Ancient DNA admixture modeling with higher confidence
GenoConnect's WGS Process
GenoConnect collects your sample via a painless at-home cheek swab, sequences your genome at 30x coverage in an accredited laboratory, and delivers 50+ reports within 10–12 weeks. Your raw sequencing data belongs to you and can be downloaded for personal research or third-party analysis.
