Tibetan Mastiff
Tibetan Mastiff genetic profile from the CanVAS Atlas. 35 dogs in the Atlas, heterozygosity 0.35. Nearest relatives, trait loci frequencies, cohort distribution.
In the atlas, the Tibetan Mastiff clusters consistently as Tibetan Mastiff (100% of the 35 dogs here). Genetic diversity is high (mean heterozygosity 0.3502), reflecting either a mixed-breed cluster or breeds with broad genetic backgrounds. At the trait loci, MSRB3 runs lower than average (45% here vs 80%); STC2 runs lower than average (43% here vs 74%).
Ranks 88 of 107 on the bottleneck severity scale, in the upper quartile of genetic diversity. Mean heterozygosity is 0.350, notably high, indicates broad genetic background.
Closest genetic neighbors in the atlas: Eurasier, Tibetan Spaniel, village dog Nepal, Mongolian Dog, and Gray Wolf.
Median lifespan is 13.0 years, about 1.8 years longer than a typical dog of 48.75 kg, an unusually positive longevity for this size.
