Cosmic medallion portrait of BULT_BULT_23695, a Bullmastiff
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.

BULT_BULT_23695

BULT_BULT_23695 is a Bullmastiff from the Spatola research cohort. One of 14,478 dogs who built the atlas.

About BULT_BULT_23695

BULT_BULT_23695 sits at the edge of the Bullmastiff cluster but still well within it.

  • Predicted small by the six body-size genes the atlas reads (IGF1, HMGA2, SMAD2, LCORL, STC2, ADAMTS17).
  • Carries one copy of the FGF4 chondrodysplasia retrogene.
  • Carrier of the RSPO2 wire-coat variant (single copy).

BULT_BULT_23695's breed

BULT_BULT_23695 sits in the Labrador Retriever cluster, with genome overlap to 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. Labrador Retriever 60%
  2. Golden Retriever 40%
