Cosmic medallion portrait of STBD_STBD_12747, a Saint Bernard
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.

STBD_STBD_12747

STBD_STBD_12747 is a Saint Bernard from the Spatola research cohort. One of 14,478 dogs who built the atlas.

STBD_STBD_12747's breed

STBD_STBD_12747 sits in the Saint Bernard 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. Saint Bernard 84%
  2. Labrador Retriever 9%
  3. Golden Retriever 6%
