摘要：

Optimum proportions selected for each sex, giving the maximum selection response up to some specified time, were investigated. Selection was carried out from a constant number of individuals scored per generation. The maximum response after t generations of selection is obtained when the number of individuals scored and the proportion selected is the same for males and females every generation. Specific situations, where the sex-ratio among scored or breeding individuals or the selected proportion of males or females is taken as given throughout the whole selection process, were studied, optimum strategies being described in each case. The procedures leading to maximum advance at the selection limit were also considered in all these situations.
