Border Terrier

Border Terrier genetic profile from the CanVAS Atlas. 59 dogs in the Atlas, heterozygosity 0.26. Nearest relatives, trait loci frequencies, cohort distribution.

What the atlas says about Border Terrier

In the atlas, the Border Terrier clusters consistently as Border Terrier (100% of the 59 dogs here). At the trait loci, SMAD2 runs lower than average (20% here vs 74%); KRT71 runs lower than average (36% here vs 91%). Dogs here sit in a relatively sparse region of the atlas, fewer close neighbors than typical.

Ranks 18 of 107 on the bottleneck severity scale, well into the upper quartile of population contraction.

Closest genetic neighbors in the atlas: Jack Russell Terrier, Airedale Terrier, Yorkshire Terrier, Rat Terrier, and Soft Coated Wheaten Terrier.

Median lifespan is 14.2 years, slightly longer than expected for the breed size (6.12 kg).
