Abstract

Using a pedigreed population of Drosophila melanogaster, various indices of individual and full-sib family information were compared for predicting progeny performance for bristle score. On average, the indices were 14% more accurate than individual performance or family mean taken separately. Index weights computed a priori from data solely on the parent's generation gave an index almost as accurate as that computed a posteriori by multiple regression of performance of progeny on parents and parent's full sibs. The value of the index was therefore as predicted from theory.
