From: Direct and correlated responses to selection for autumn lambing in sheep
Experimental design to evaluate improvement of autumn lambing by selection [11]. Arrows indicate the flow of replacement ewe lambs in the three lines. Replacement ewes and rams in the S (selection) and GC (genetic control) lines were produced within the lines. Unselected replacement ewes for the EC (environmental control) line were produced in the GC line and transferred to the EC line for evaluation
