- SUMMARY: The biological basis for meat production in livestock animals is localized in the muscles, where lean meat production is under the genetic control of tissue-specific and more ubiquitously operating genes. The muscle tissue-specific MyoD gene family is at the centre of the genetic regulation of myoblast proliferation and differentiation into myofibres. The regulation of embryonic muscle tissue formation (development) by the MyoD genes is duscussed in the context of livestock animals used in meat production. The possibility that the MyoD genes could be useful candidate genes for breeding is discussed. It is concluded that marker assisted selection (MAS) using markers in functional genes is advantageous over MAS using associated markers.
