What the atlas says about Norwich Terrier

In the atlas, the Norwich Terrier clusters consistently as Norwich Terrier (100% of the 14 dogs here). At the trait loci, MSRB3 runs lower than average (0% here vs 80%); FGF4_retrogene_CFA18 runs lower than average (14% here vs 77%). Dogs here sit in a relatively sparse region of the atlas, fewer close neighbors than typical.

High breed predictability score (0.86), individual dogs of this breed reliably cluster together genetically. Only 14 dogs of this breed in the atlas, modestly sampled.
