Dingo Bigdesert
19 Dingo Bigdeserts in the atlas. Every number on this page has a source.
19 Dingo Bigdeserts in the Sniff Atlas. Population-genetic snapshot, Mendelian carrier frequencies from Donner 2023, and the data substrate's release version, sample sizes, and evidence tier on every claim.
In the atlas, the Dingo Bigdesert clusters consistently as Dingo Bigdesert (100% of the 19 dogs here). Genetic diversity is low (mean heterozygosity 0.0676), suggesting a tightly-related local population. At the trait loci, RSPO2 runs lower than average (0% here vs 55%); BMP3 runs higher than the atlas average (100% here vs 66%).
Mean heterozygosity is 0.068, low even for a closed-stud breed. High breed predictability score (12.79), individual dogs of this breed reliably cluster together genetically. Only 19 dogs of this breed in the atlas, modestly sampled.
Closest genetic neighbors in the atlas: Dingo West, Dingo Captive, Dingo South, Dingo East, and Dingo Hybrid.

What does the genome say about how a Dingo Bigdesert looks?
Dingo Bigdeserts look the way they do because of a small set of fixed and near-fixed morphology genes that, taken together, define the visible breed. Each translation below pairs the gene with the trait an owner actually sees, the breed's allele frequency at that locus, and a one-clause causal phrase.
Size and build
IGF1 is at 0% for the small-body allele, leaving the breed firmly in the larger end of the dog body-size spectrum.
HMGA2 is at 0%, leaving most of the size signal to other loci in the panel.
SMAD2 is at 0%, leaving the height signal mostly to other size genes.
LCORL is near-fixed at 100%, the NCAPG/LCORL height locus that is one of the strongest single contributors to canine body size.
STC2 sits at 74%.
ADAMTS17 is at 0%, the lower-frequency allele in this breed.
Leg length
The FGF4 retrogene on chromosome 18 is near-fixed in this breed at 100%. This is the leg-length variant. The breed is fully committed to the long-legged form rather than the short-legged Corgi-and-Dachshund body plan.
The FGF4 retrogene on chromosome 12 is at 0%, leaving most of this breed clear of the chondrodystrophic intervertebral disc disease risk.
Coat type, length, and color
RSPO2 is at 0% for the furnishings allele. The breed does not carry the eyebrows-and-mustache pattern of Wheatens, Schnauzers, or wire-haired terriers.
FGF5 is at 0% for the long-coat variant, which keeps the breed in the short-coated form.
KRT71 is at 0% for the wavy/curly variant, leaving the breed's coat straight.
MC1R is at 0% at the representative SNP, leaving the breed in the black-to-brown coat range under the dominant E allele.
Ears
MSRB3 is at 100% for the drop-ear allele, the genetic basis of the breed's signature dropped ear set.
Skull shape
BMP3 is at 100%, contributing to the breed's brachycephalic skull shape.
SMOC2 is at 0%, leaving the breed in the long-headed dolichocephalic form.
Where every number on this page came from.
This page draws on three primary data sources. Carrier frequencies for the Mendelian section come from Donner et al. 2023 (CC-BY-4.0). We grade these data at evidence Limited because the cohort is a direct-to-consumer ascertainment, which biases toward owners who chose to test their dogs. The panel also uses tag-SNP proxies for some variants rather than direct causal-variant assays. Limited is a study-design grade, not a quality grade: the Donner cohort is the largest open canine-genotype dataset in existence and we are grateful for it. We rate the confounding MEDIUM.
Population-genetic dimensions (heterozygosity, intra-breed PCA distance, nearest neighbors, trait-locus frequencies) come from CanVAS (Brundage 2026), harmonized through the Sniff Atlas. The exact release date and verification commit are pinned at the bottom of the page so a researcher can trace a number back to a specific snapshot. The disease-gene-variant graph comes from OMIA (Online Mendelian Inheritance in Animals; Nicholas, Tammen, and the Sydney Informatics Hub at the Sydney School of Veterinary Science, The University of Sydney; retrieved April 2026, DOI 10.25910/2AMR-PV70).
What this page does not yet have. Inheritance modes and per-disease penetrance evidence from Donner 2023 are now in the structured data for every variant the panel covers. Mondo, OMIM, Ensembl, and HGNC cross-references on gene pages remain pending — they arrive in December 2026 alongside the imputed 9.67M-variant CanVAS dataset via the OMIA SQL dump absorption. Until then, gene IDs carry NCBI Gene and OMIA phene URLs only; the wider human-homolog and disease-ontology cross-reference set fills in with that release.
