Cosmic medallion portrait of C_TMf_C_TMf4, a Tibetan Mastiff
AI portrait
About this portrait

This portrait was algorithmically built from this dog's genome: their genotype at 8 morphology loci (coat length, curl, color, ear set, body size, head shape, skull, furnishings) plus their position within the 14,478-dog atlas. The same dog always reproduces the same portrait. A different dog with different alleles gets a different portrait.

C_TMf_C_TMf4

C_TMf_C_TMf4 is a Tibetan Mastiff from the Chen research cohort. One of 14,478 dogs who built the atlas.

About C_TMf_C_TMf4

C_TMf_C_TMf4 sits well inside the Tibetan Mastiff cluster - a fairly typical example.

  • Predicted large by the six body-size genes the atlas reads (IGF1, HMGA2, SMAD2, LCORL, STC2, ADAMTS17).
  • Carries both copies of the FGF4 chondrodysplasia retrogene - the short-leg variant in Dachshund, Pembroke Corgi, Basset Hound.
  • Carrier of the RSPO2 wire-coat variant (single copy).

C_TMf_C_TMf4's breed

C_TMf_C_TMf4 sits in the Tibetan Mastiff cluster, with genome overlap to Golden Retriever, and Labrador Retriever - sister breeds nearby in the atlas.

Breed similarity from non-negative least squares against 91 breed centroids in PCA-256 space, corrected for atlas sample-size imbalance. Without correction, Goldens (22% of the atlas) leak into every dog's raw NNLS breakdown; with it, the bias falls out. Raw fractions stay in the dataset for re-derivation. Methodology.

  1. Tibetan Mastiff 81%
  2. Golden Retriever 11%
  3. Labrador Retriever 9%
