[QUOTE="robert, post: 771025, member: 9171"] it is 35 sire daughter matings. Certainly in Angus many of the highly used sires are acceptable for use on heifers so they get used in commercial heifer development programs routinely, you simply dna type 40 or so daughters of a given sire, breed them back to the sire and you should end up with 35 separate sire/daughter pregnancies. If a problem shows up then go from there, if no problems there is a 99% statistical liklihood that the sire is free of any recessive traits. What is more expensive? The perpetuation of lethal recessives for generations and then having to go back and clean house or a pro-active solution with sires of breed wide influence? [/QUOTE]
