This publication is Number 11 in the series Texas Adapted Genetic Strategies for Beef Cattle. Bits of DNA called markers can be useful in determining possible specific performance of a particular trait; these markers are typically located near genes associated with trait heritability. Testing for these markers can facilitate selective breeding. Several well-known benefits of DNA testing include validation of parentage, testing for diseases or genetic defects, and testing for qualitative inherited traits. Testing for markers and other QTLs of interest can be done at or shortly after birth, reducing the time and cost involved in collecting data from older animals of from carcasses. With each animal tested, DNA testing will provide more information, especially about traits that are difficult tp measure or that are sex limited. Such testing also provides greater opportunities to select for traits with genetic antagonisms. (6 pp., 1 table) By: Joseph C.
