Australian scientists announced a breakthrough on Thursday in the hunt for the perfect steak: a DNA test that identifies cattle carrying a special tenderness gene.

CSIRO said the “GeneSTAR tenderness test” would permit farmers to selectively breed cattle that consistently produce tender beef.

The test, which will cost farmers 60-90 dollars (35-50 US) per animal, uses DNA extracted from live cattle to identify two variants of a gene linked to the enzyme calpastatin.
