[QUOTE="brihop, post: 966576, member: 18530"] I know a few people that breed heifers back to sire without problems... but, those inbred calves are all sold, so it never goes any further. However, it seems to me that the "lesser of the 2 inbreeding evils" would be to breed a bull to his half sister, that way there is still only 50% of the sires blood in the mix. When you breed a heifer back to her sire there is 75% of sire blood, making the resulting calves more inbred than the 1/2 brother/sister option. Or am I missing some technical genetic lesson here?
