Abstract

Quantitative geneticists are interested in the difference between the expected and realized responses from selection. Many experiments have been performed to test theories of selection for a single trait (Falconer, 1960). Very little experimental examination of selection index theory has occurred. Thus, the present study was iniatiated to examine respones to selection for two traits: body weight at preweaning age (12 days) and body weight at maturity (42 days). The results from this experiment ere intended to elucidate correlated responses from single- and multiple-trait selection.
