title: Response to partial selection on clean fleece weight in south Australian strong-wool Merino sheep. III. Genetic distance between flocks.
abstract: Divergence over time in flocks selected for clean fleece weight and for fecundity is measured by gene frequency changes at the R-r-i blood group, haemoglobin, and transferrin loci. No unequivocal effect of selection is demonstrable. Problems of interpretation even in flocks of known history are discussed.
