[QUOTE="ANAZAZI, post: 1210945, member: 7541"] Prepotency is derived from linebreeding. Consistency is derived from prepotency. Heterosis IS NOT derived from prepotency. Heterosis IS derived from differences between the genetics of Dam and Sire. Yes; heterosis might be stronger if the parent stock is inbred, but only because there is more for the heterosis to "cure". Cross an outcrossed bull (breed A) with an outcrossed cow (breed B), or a linebred bull (breed A) with a linebred cow (breed B), the progeny in both crosses will be at the same production level, but the cross from linebred parents will be more elevated from its parents production level. Thus, the fact that some of these cattle were linebred did not make any extra production. [/QUOTE]
