Village Dog China
9 Village Dog Chinas in the atlas. Every number on this page has a source.
9 Village Dog Chinas 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 village dog China clusters consistently as village dog China (100% of the 9 dogs here). Genetic diversity is high (mean heterozygosity 0.3798), reflecting either a mixed-breed cluster or breeds with broad genetic backgrounds. At the trait loci, BMP3 runs lower than average (0% here vs 66%); STC2 runs lower than average (17% here vs 74%).
Mean heterozygosity is 0.380, notably high, indicates broad genetic background. High breed predictability score (2.43), individual dogs of this breed reliably cluster together genetically. Only 9 dogs of this breed in the atlas, every individual contributes outsized weight to the breed's computed profile.
Closest genetic neighbors in the atlas: Thai Ridgeback, village dog Armenia, village dog Tajikistan, village dog Kazakhstan, and village dog East Russia.

What does the genome say about how a Village Dog China looks?
Village Dog Chinas 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 sits at 39%. HMGA2 is a chromosome-10 size locus that acts together with IGF1, and intermediate frequencies reflect partial commitment to the dominant size variant.
SMAD2 sits at 50% at the chromosome-7 height locus.
LCORL is near-fixed at 94%, the NCAPG/LCORL height locus that is one of the strongest single contributors to canine body size.
STC2 is at 17%, leaving the growth-axis signal to other loci.
ADAMTS17 sits at 50%. ADAMTS17 is a body-size locus also linked to lens disorders.
Leg length
The FGF4 retrogene on chromosome 18 sits at 61%. This is the leg-length variant. The intermediate frequency means some dogs in this breed carry the short-legged allele and some do not.
The FGF4 retrogene on chromosome 12 sits at 56%, the chondrodystrophic variant.
Coat type, length, and color
RSPO2 sits at 56% for the furnishings variant. Furnishings (the eyebrow-and-mustache pattern seen in Schnauzers and Wheaten Terriers) vary across the population at this intermediate frequency, and visible expression depends on the specific allele combination each dog carries.
FGF5 sits at 67% for the long-coat variant. Coat length is influenced by other loci as well, so intermediate FGF5 frequencies do not always correspond to intermediate visible coat lengths.
KRT71 is near-fixed at 94% for the wavy/curly variant. Coat curl phenotype varies across breeds at this fixation depending on modifier loci, and visible expression is not always curled even when the locus is fixed.
MC1R sits at 83% at the representative SNP. MC1R controls the switch between red-to-gold pigment and black-to-brown pigment, with the e/e homozygous genotype producing the gold-to-red spectrum. Substrate frequencies at this SNP depend on the array's polarity, so visible coat color in the breed is a more reliable indicator than this single number.
Ears
MSRB3 is at 28% for the drop-ear allele, keeping the breed's ears upright and prick.
Skull shape
BMP3 is at 0%, keeping the breed in the dolichocephalic, long-headed form.
SMOC2 sits at 44%, contributing to the breed's moderate head shape.
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.
