Sammanfattning

Properties of deregression for a low heritability trait (clinical mastitis in Sweden with heritability of 0.02) and effects of using different definitions of genetic groups in within-country deregression compared with the across-country analysis were studied. The deregression procedure was satisfactory, and the effects of different phantom parent grouping in within-country deregression compared with across-country analysis were negligible here.
