Cosmic medallion portrait of SA_1_SA_16AS, a Village Dog South Africa 1
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.

SA_1_SA_16AS

SA_1_SA_16AS is labelled Village Dog South Africa 1 in the Spatola cohort - a catch-all CanVAS label, not a literal ancestry call. One of 14,478 dogs who built the atlas.

About SA_1_SA_16AS

SA_1_SA_16AS sits at the edge of the Village Dog South Africa 1 cluster but still well within it.

  • Predicted large by the six body-size genes the atlas reads (IGF1, HMGA2, SMAD2, LCORL, STC2, ADAMTS17).
  • Carries one copy of the FGF4 chondrodysplasia retrogene.
  • Smooth coat. No wire-furnishings variant at RSPO2.

SA_1_SA_16AS's breed

SA_1_SA_16AS's genome decomposes mostly into Labrador Retriever, with additional weight on Golden Retriever.

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. Labrador Retriever 59%
  2. Golden Retriever 41%
