Scottish Terrier

Scottish Terrier genetic profile from the CanVAS Atlas. 33 dogs in the Atlas, heterozygosity 0.28. Nearest relatives, trait loci frequencies, cohort distribution.

What the atlas says about Scottish Terrier

In the atlas, the Scottish Terrier clusters consistently as Scottish Terrier (100% of the 33 dogs here). At the trait loci, HMGA2 runs lower than average (3% here vs 56%); ADAMTS17 runs higher than the atlas average (100% here vs 54%). Dogs here sit in a relatively sparse region of the atlas, fewer close neighbors than typical.

Ranks 26 of 107 on the bottleneck severity scale, well into the upper quartile of population contraction.

Closest genetic neighbors in the atlas: West Highland White Terrier, Norwich Terrier, Cairn Terrier, Fox Terrier Wire, and Norfolk Terrier.
