In the present study we determined the role of these factors in producing the response to artificialselection for body size. Survival rates of mutant genes under artificialselection using individual and family information. The information inherent in continuous reaction norms seems not, however, to have been systematically exploited in artificialselection programmes. Plant breeding literature generally assumes a human-modified environment and artificialselection. Information about phenotypic plasticity can be used to improve the efficiency of artificialselection. Our model can be used to give some insights into the question of the evolution of the genetic variance under artificialselection. Several artificialselection strategies could be used to increase the effectiveness of purging. There are models describing the interaction between natural selection and artificialselection for a quantitative character in a finite population. Similarly, the artificialselection of responses is not at issue in contemporary accounts of behavior. The selection index developed here is a simple illustration of how information about phenotypic plasticity can be exploited in artificialselection. In this respect, immune selection is like artificialselection in which a breeder selects with the intention of achieving a particular result. It provides an elegant statistical framework for understanding the relation between phenotype and genotype, and the response of populations to natural and artificialselection. Information on the genetics of environmental sensitivity can be incorporated into standard statistical methods for breeding in order to improve the efficiency of artificialselection. Empirical evidence against the infinitesimal view has also come from artificialselection experiments.
