Modern molecular methods have generated vast quantities of new information which has gone largely unused by scientists applying quantitative genetic theory to the improvement of farmed livestock. This new information has a lot to offer in selection programmes but new methods will need to be developed and new sources of data will need to be harnessed in order to fully utilize it. A more detailed understanding of how animals function at a molecular level has challenged some of the basic concepts of quantitative genetics, particularly the way that environmental factors affect traits. Computers will become cheaper and more powerful, molecular methods will become cheaper and more routine. Thus, given the right methodology, conditions will be right to fully exploit these sources of data provided that action is taken now to prepare for the new scenario.
