Geneticlinkagemapsenablescientists toidentify regionsofthegenome thatinfluenceproduction related traits. Sufficientnumber of polymorphic markers (5 1800) are available for a genome-wide quantitative trait loci (QTL) search and subsequent use of markers forselection.Selectionforcarcass traitshasbeen limitedb-xausecurrent marketsystemsdonotprovidecarcass information to thecattle producer. Information obtained from mapping studies will allow producers to select for carcass traits and other traits that are difficult and expensive to measure in production settings. Mapping information will also be used to identify the molecular mechanisms controlling the genetic component of carcass traits and other quantitative traits.
