This is a question for those who know a lot about Line One and is merely something that I have been curious about for a few months. This is not intended to cause argument or hard feelings.
Some time ago I came across a pedigree for a bull from the Florida Experiment station that is Florida Station breeding for several generations, and then as far as I have checked, appears to go back to Line 1 genetics on all ancestors previous to the Florida breeding. I have not looked at the pedigree closely for a while so I may be mistaken on that, but I remember that all ancestors that I checked went back to Station bred Line 1 breeding.
You might wonder so what? Well, the interesting thing is that this pedigree from Florida is from a Polled bull out of what appears to be a horned sire and a first generation spontaneously occurring Polled dam who was out of horned parents. I don't care to say who this bull is in order to try to avoid arguments about whether or not this Polled bull is legitimate or not.
Out of curiosity, I did some digging into the pedigree of this bull and found an oddity that I would like to put here for discussion. I found a bull in the pedigree several times named:
L1 DOMINO 253 (9041928)
253's maternal grand dam's sire is: AA DOMINO 2 (P36000423) born in 1945. Now, the news article about Ft. Keogh in 2009 indicates that the Line 1 herd has been closed since 1934 which is one discrepancy in addition to the Polled designation of AA Domino 2 whose daughter, A-A LADY 8 (4506253), and 253's maternal grand dam, is horned. 253 is several times in the pedigree that I was looking at, and if accurate means that the Polled gene was introduced long ago, but only now has manifested itself.
Since this makes little sense it would be easy to chalk this all up to an inaccurate database for the online records of AHA, except that another different daughter of AA Domino 2 has appeared in a different Station bred Line 1 pedigree, and this cow is named: A-A LADY (4506246) who also has a horned designation and was born in 1945.
So my trivia questions are: 1.) How long has the Line 1 herd been completely closed?
2.) Did the Line 1 Station ever buy either AA Domino 2, or any daughters of AA Domino 2.
3.) Is the Polled designation for AA Domino 2 correct?
The pedigree of AA Domino did not appear to have anything behind him to cause him to be designated Polled, so perhaps it is just an error. The registration number is odd as well. Or perhaps he is an example of a spontaneously appearing Polled animal.
As an aside, I have found a paper referring to an earlier Line 1 conversation about color markings with color pictures which I will add here for those who are interested.
