[QUOTE="fourstates, post: 392048, member: 5918"] I heard: If it's done on purpose, it's called linebreeding, by accident, it's called inbreeding. Father, daughter/ mother,son only share 50% of the same genes. Even siblings unless they are identical twins, still vary genetically. Unless both parents carry certain traits (good or bad) the odds are the mating will not display any problems. If you continue to reduce the gene pool (by continued generational inbreeding) eventually defects will show up. Linebreeding never causes genetic defects, it just increases the odds they will show up. Culling is the most important factor in trying to get a certain trait to dominate, because you can only manage phenotype (what you see) not genotype (genes carried). [/QUOTE]
