Two libraries were run on two separate SMRT cells using the Sequel system, and yielded ~500,000 reads each with mean read lengths of 2452 and 451bp. Dogs have 78 chromosomes; 39 come from the father and 39 come from the mother. In human clinical genomics, SVs spanning coding and/or noncoding sequence have been responsible for a range of maladies including cardiac anomalies (OMIM 192430) and intellectual delay and autism (OMIM 608636).

The vast majority of pedigree dog breeds have been selectively bred over the last 200 years, although the origin of many of the breeds is uncertain. In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. In any given asexually reproducing species, the chromosome number is always the same. This can be fairly straightforward when studying genes that control appearance, however, it is much more difficult when studying dog disease or behavior (Spady et al. 10x breed-matched ISR data were downloaded for 25 individuals (Supplementary Table9) and mapped to GSD_1.0 (BWA mem, default settings).
