Genetics glossary

Plain-language definitions of every trait, gene, and DNA marker behind Biome’s genetic tests. 124 traits, 141 genes, and 117 markers — each one defined, rated by strength of evidence, and cross-linked so you can follow a gene to the traits it shapes and the markers that read it.

Everything here is educational context, framed as tendencies and predispositions — not a diagnosis and not medical advice. See the DNA test and whole genome sequencing for what each product reads.
