Cattle - Cattle Genome

Cattle Genome

In the April 24, 2009, edition of the journal Science, a team of researchers led by the National Institutes of Health and the US Department of Agriculture reported having mapped the bovine genome. The scientists found cattle have about 22,000 genes, and 80% of their genes are shared with humans, and they share about 1000 genes with dogs and rodents, but are not found in humans. Using this bovine "HapMap", researchers can track the differences between the breeds that affect the quality of meat and milk yields.
