Japanese Chin

Japanese Chin genetic profile from the CanVAS Atlas. 8 dogs in the Atlas, heterozygosity 0.25. Nearest relatives, trait loci frequencies, cohort distribution.

What the atlas says about Japanese Chin

In the atlas, the Japanese Chin clusters consistently as Japanese Chin (100% of the 8 dogs here). At the trait loci, FGF4_retrogene_CFA18 runs lower than average (0% here vs 77%); SMAD2 runs lower than average (0% here vs 74%). Dogs here sit in a relatively sparse region of the atlas, fewer close neighbors than typical.

Only 8 dogs of this breed in the atlas, every individual contributes outsized weight to the breed's computed profile.

Closest genetic neighbors in the atlas: Lhasa Apso, Finnish Spitz, American Eskimo Dog, Kuvasz, and Curly Coated Retriever.
