Pekingese

Pekingese genetic profile from the CanVAS Atlas. 26 dogs in the Atlas, heterozygosity 0.31. Nearest relatives, trait loci frequencies, cohort distribution.

What the atlas says about Pekingese

In the atlas, the Pekingese clusters consistently as Pekingese (100% of the 26 dogs here). At the trait loci, FGF4_retrogene_CFA18 runs lower than average (0% here vs 77%); SMAD2 runs lower than average (4% here vs 74%). Dogs here sit in a relatively sparse region of the atlas, fewer close neighbors than typical.

Only 26 dogs of this breed in the atlas, modestly sampled.

Closest genetic neighbors in the atlas: Shih Tzu, Tibetan Spaniel, Tibetan Terrier, Pug, and Chihuahua.
