Báo cáo sinh học: "Prediction of response to selection within families" potx

... short term, selection on within- family deviation is expected to give higher responses, but in the long term, selection within families is expected to give higher responses ... effectif génétique Only one-half of the additive genetic variance is expressed within families, so selection within families is not usually predicted to lead to...

... aims of this study were: (a) to estimate the selection response in the ratio of gonadal fat pad to body weight, a trait highly correlated with the total percentage of body fat; and (b) to estimate ... estimate the magnitude of the initial rates of response to selection. Long-term experiments are useful for measurement of changes in the rates of response or varia...
