This tool compares — genetic variants linked to visible physical traits — pigmentation, hair texture, height, and facial morphology — against reference populations from 1000 Genomes, HGDP, and SGDP. Each population gets a frequency profile at every variant, and your genotypes are scored against each one. Variants that differ more across populations carry more weight. The tree shows how populations cluster by these traits. After you upload, you're placed on it based on your overall scores. Because pigmentation and morphology track broad geography, results loosely reflect ancestry — but this is a narrow slice of your genome and is not comparable to a full ancestry test. Show all SNPs
