CORRELATED RESPONSE TO SELECTION DURING SELFING

Theory for predicting the correlated response to selection during self ing is proposed and then validated by computer simulation. Pairs of ch aracters, correlated either by pleiotropy or linkage, were simulated; Linkage was in coupling, repulsion or a combination of the two. The co rrelated responses to both family and sib selection were examined. Com parison of expected with the average observed correlated responses sho wed the accuracy of the theory, but the observed sampling variation in dicated that a wide variability of individual responses is to be expec ted in practice.
