The bovine genome is similar in size to the genomes of humans, with approximately 3 billion base pairs and approximately 25,000 genes. Sequences for full-length cDNA clones derived from 28 different bovine tissues were used as evidence in construction of an official set of bovine genes, as part of the collaboration between the BC Cancer Agency Genome Sciences Centre, BCCA in Vancouver and the University of Alberta. The cattle genome sequence provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production. The $6M project was part of the larger Bovine Genome Sequencing Project, a $70M international initiative to sequence the bovine genome led by the National Human Genome Research Institute.
