A maternal effect in animals can result from three sources: first, the mother may pass factors to its o

Introduction,ttests very clearly to the presence of genetic variation within species. This has been demonstrated further by numerous common garden experiments in which individuals from different populations are grown under the same set of conditions [Table 1.1; note that nongenetic, maternal effects require that

The Genetic Correlation, traits are not inherited as independent units, but that several traits tend to be associated with each other. This phenomenon can arise in two ways: first, a subset of the genes that influence one trait may also influence another trait, a phenomenon known as ., and second, the genes may act indepen

Directional Selection,perspective of changes in the mean value of a quantitative trait (the other two types are discussed in CHAPTER 9). The term . applies to selection in which the mean value of the parents which contribute to the next generation differs from that of the population from which the parents are drawn. The

Directional Selection and the Correlated Response,n that suite of traits which determines overall fitness. Further, even when there is direct selection on only one trait, there may be significant effects on other traits because of a genetic or phenotypic correlation between the selected and unselected traits. In this Chapter, I review the theory of
