I think that most of all, this work was important because it established the feasibility of sequencing entire genomes with massively parallel / short read technologies and getting valuable results from it. (massgenomics.org)
That procedure looks for a specific problem in a few embryos, not entire genomes from dozens of them. (medicalxpress.com)
Whole genome sequencing is done in the lab so the researchers can look at the dog's entire genome at one time. (pawster.com)
