Clearly, genome contiguity as well as gene and regulatory element annotation from a range of diverse breeds and tissues are all required to translate association to causation. This allows them to hybridise freely (barring size or behavioural constraints) and produce fertile offspring. & OBrien, S. J. 467, 1928 (2019).

Much recent interest in dog genetics has resulted from a desire on the part of veterinary scientists to reduce the problem of inherited diseases in pedigree dogs. Putative telomere sequences were defined as at least 12 consecutive repeats with less than 11 variant bases between each, and multiple sequences were merged if within 100bp. Fischer

For both human and mouse projects, the de novo sequence assembly of multiple individuals from different population backgrounds has revealed novel sequence not found in the single (hybrid in the case of human) species reference, and facilitated the search for population-specific variants which likely contribute to traits of interest, including within the highly polymorphic immune gene clusters46,47.

Dogs therefore have potential as animal models for gene therapy experiments, and although dogs have some disadvantages as experimental animals, they may be suitable intermediate-sized models with their greater lifespan allowing longer term studies than are possible in mice. The sequence of each gene is called its "code." Cluster 2 included largely mastiff-type dogs with big, boxy heads and large, sturdy bodies. Human gene therapy failures using therapies developed in mice may be due in part to differences in physical size and longevity between mouse and human.
SNPs, or single nucleotide polymorphisms, represent single bases in the genome that are frequently mutated. Science 352, aae0344 (2016).
