Genome-wide SNP and haplotype analyses reveal a rich history underlying dog domestication - PubMed

Branch colour indicates the phenotypic/functional designation used by dog breeders,. A dot indicates ≥95% bootstrap support from 1,000 replicates. a, Haplotype-sharing cladogram for 10-SNP windows (n = 6 for each breed and wolf population). b, Allele-sharing cladogram of individuals based on individual SNP loci. c, Haplotype-sharing phylogram based on 10-SNP windows of breeds and wolf populations. d, Allele-sharing phylogram of individual SNPs for breeds and wolf populations. For c and d, we note breeds where genetic assignments conflict with phenotypic/functional designations as follows: 1, Brussels griffon; 2, Pekingese; 3, pug; 4, Shih-tzu; 5, miniature pinscher; 6, Doberman pinscher; 7, Kuvasz; 8, Ibizian hound; 9, chihuahua; 10, Pomeranian; 11, papillon; 12, Glen of Imaal; 13, German shepherd; 14, Briard; 15, Jack Russell; 16, dachshund; 17, great schnauzer; and 18, standard schnauzer. Gt, great; mtn, mountain; PBGV, petit basset griffon vendeen; pin., pinscher; ptr, pointer; ret., retriever; shep., shepherd; sp., spaniel; Staf., Staffordshire; std, standard; terr., terrier.
