Xoloitzcuintli
Xoloitzcuintli genetic profile from the CanVAS Atlas. 20 dogs in the Atlas, heterozygosity 0.36. Nearest relatives, trait loci frequencies, cohort distribution.
In the atlas, the Xoloitzcuintli clusters consistently as Xoloitzcuintli (100% of the 20 dogs here). Genetic diversity is high (mean heterozygosity 0.3567), reflecting either a mixed-breed cluster or breeds with broad genetic backgrounds. At the trait loci, HMGA2 runs lower than average (25% here vs 56%).
Ranks 92 of 107 on the bottleneck severity scale, in the upper quartile of genetic diversity. Mean heterozygosity is 0.357, notably high, indicates broad genetic background. Low breed predictability score (0.25), individual dogs of this breed vary widely in genetics, suggesting active substructure or sub-population diversity. Only 20 dogs of this breed in the atlas, modestly sampled.
Closest genetic neighbors in the atlas: Schipperke, Bichon Frise, Ibizan Hound, Brittany, and Miniature Poodle.
Median lifespan is 14.0 years, about 1.9 years longer than a typical dog of 17.5 kg, an unusually positive longevity for this size.
