Coverage-aware
A missing marker is reported as missing—never interpreted as the reference genotype.
Small questions.
Transparent answers.
Six focused calculators for established genetic traits. Upload an unmodified commercial DNA export, inspect every marker used, and see exactly where the evidence stops.

ABO blood type
Common A, B, AB, or O inference from a three-marker haplotype panel.
Open calculator →026-marker panel
Eye colour
Read the six established eye-colour markers used by the IrisPlex panel, with a conservative result that keeps intermediate colours and missing data visible.

Lactase persistence
Check the common Eurasian lactase-persistence enhancer plus functional variants documented in African and West Asian populations.
Open calculator →041 metabolism + 1 response marker
Caffeine metabolism
Interpret CYP1A2 rs762551 enzyme inducibility and, when available, keep the separate ADORA2A caffeine-response marker in context.
Open calculator →053-marker haplotype
Bitter taste
Resolve the common TAS2R38 PAV and AVI haplotypes that shape sensitivity to the laboratory bitter compounds PTC and PROP.
Open calculator →061 functional variant
Earwax type
Read the strongly predictive ABCC11 rs17822931 variant associated with wet or dry earwax, with strand orientation made explicit.

No single SNP tells your whole story.
Evidence-scoped
Each result describes the phenotype actually studied, with population and environmental limits visible.
Inspectible
The rsIDs, raw calls, model role, research references, and version are all exposed.
Population analysis
Traits are a handful of loci. Ancestry uses the genome.
