[QUOTE="Brandonm22, post: 688678, member: 7645"] The term you are looking for is "inbreeding depression". It is the main reason why performance breeders are always looking for outcrosses. I am not well versed on the subject but as I understand it it is the exact opposite of heterosis. In heterosis you get a slightly better performance than one would expect from the average of the two parents. With the inbreeding depression effect a closely mated individual performs worse than you would expect from the average of the two parents. I think most experienced linebreeders claim this fades away after the first 3 generations in a linebreeding regimen. [/QUOTE]
