Individual inbreeding coefficients were computed in three lines of a selection experiment by using the algorithm of Quaas (1976). The mean inbreeding was about 2% at the end of the experiment and no significant difference was found among lines selected for increased fleece mass and visual overall excellence, and an unselected control. Evidence suggests that inbreeding could have had no appreciable effect on selection response or level of produc­tion and reproduction in the three lines.
