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.

STAF_STAF_03163

STAF_STAF_03163 is a Staffordshire Bull Terrier from the Spatola research cohort. One of 14,478 dogs who built the atlas.

About STAF_STAF_03163

STAF_STAF_03163 sits at the edge of the Staffordshire Bull Terrier cluster but still well within it.

  • Predicted large by the six body-size genes the atlas reads (IGF1, HMGA2, SMAD2, LCORL, STC2, ADAMTS17).
  • Standard leg length. No chondrodysplasia retrogene variant.
  • Carrier of the RSPO2 wire-coat variant (single copy).
STAF_STAF_03163's breed

STAF_STAF_03163 sits in the Staffordshire Bull Terrier cluster, with genome overlap to Labrador Retriever, and Golden 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. Staffordshire Bull Terrier 84%
  2. Labrador Retriever 9%
  3. Golden Retriever 7%
