Trait genes
The 15 loci Sniff reads on every dog
These are the morphology loci behind the per-dog trait calls in the Atlas. Each gene's page shows which breeds carry the variant most heavily, the biological direction of effect, and the methodology behind the call, including the published caveats (FGF4 retrogene polarity, SMOC2 polygenicity for brachycephaly).
