[QUOTE="Brandonm22, post: 707918, member: 7645"] HerefordSire makes a good point. If performance has been bound up for generations through a linebreeding program where linebreeding depression has built up then outcrossing to an unrelated line CAN produce a short term performance boost akin too heterosis. Unlike heterosis though it would be really hard to get that effect more than once. Once you have added heterozygosity adding a third line from the same breed is going to do almost nothing. [/QUOTE]
