Havanese

Havanese genetic profile from the CanVAS Atlas. 54 dogs in the Atlas, heterozygosity 0.33. Nearest relatives, trait loci frequencies, cohort distribution.

What the atlas says about Havanese

In the atlas, the Havanese clusters consistently as Havanese (100% of the 54 dogs here). Genetic diversity is high (mean heterozygosity 0.33), reflecting either a mixed-breed cluster or breeds with broad genetic backgrounds. At the trait loci, FGF4_retrogene_CFA18 runs lower than average (2% here vs 77%); SMAD2 runs lower than average (22% here vs 74%).

Mean heterozygosity is 0.330, notably high, indicates broad genetic background. Low breed predictability score (0.29), individual dogs of this breed vary widely in genetics, suggesting active substructure or sub-population diversity.

Closest genetic neighbors in the atlas: Dachshund, Toy Poodle, Miniature Dachshund, Beagle, and Pug.

Median lifespan is 14.5 years, slightly longer than expected for the breed size (4.5 kg).
