American Hairless Terrier genetic profile from the CanVAS Atlas. 10 dogs in the Atlas, heterozygosity 0.40. Nearest relatives, trait loci frequencies, cohort distribution.

What the atlas says about American Hairless Terrier

In the atlas, the American Hairless Terrier clusters consistently as American Hairless Terrier (100% of the 10 dogs here). Genetic diversity is high (mean heterozygosity 0.4042), reflecting either a mixed-breed cluster or breeds with broad genetic backgrounds. At the trait loci, SMAD2 runs lower than average (10% here vs 74%); HMGA2 runs lower than average (0% here vs 56%).

Mean heterozygosity is 0.404, notably high, indicates broad genetic background. High breed predictability score (2.38), individual dogs of this breed reliably cluster together genetically. Only 10 dogs of this breed in the atlas, modestly sampled.

Closest genetic neighbors in the atlas: Australian Terrier, Silky Terrier, village dog Nz South, village dog Nz North, and Bedlington Terrier.
