Indirect genetic effects (IGE) are genetic effects of an individual on the trait values of other individuals in the same species. These effects are also known as social genetic effects and associative genetic effects. Although the concept first arose in the agricultural genetics literature in the 1960s, it did not receive much attention outside that community until the late 1990s. Since then, there has been a great deal of development of the theoretical literature, which has emphasized that IGE provides a unifying framework for traditional quantitative genetics, maternal and paternal genetic effects, inclusive fitness, and multilevel selection.
AGA President Kimberly Hughes’ symposium will bring together empiricists, statisticians, and theoreticians using this concept to investigate both applied and basic research questions. Other speakers will focus on model organisms, agricultural systems, and natural populations of non-model species.
