[Jacob-list] Re: Lilacs

[Neal and Louise Grose]

It would have been simpler if all crosses came out all black. I think that it is a mistake to get the discussion of the piebald gene(s) mixed up with the base color. 'Piebald' seems to be in a separate series of genes. I think that the difference in piebald is coming from differences in bloodlines and not in the base colors, since we also get clear piebald in crossing black and white Jacob rams on white ewes. My guess is that the dominant piebald gene comes from inbred populations of Jacobs where the gene was reinforced by additional copies or something.  By the way, I have seen Jacob X Barbados lambs at Edd Bisell's, they had three colors, black extremities and all sots of stuff.

  I am interested in the fact that there are both piebald and black lambs appearing here.  So far, the evidence I've seen, which isn't much have piebald results when crossing lilac jacobs to moorit rams, and black lambs when crossing that moorit ram to black and white jacobs: is that true?  And if so, what does that say about piebald?  If anything...

    Dan,
        You have done as good of a job as any that I have seen in sorting this stuff out. I am looking at our results in test crossing and trying to plug in answers to the following:
    1) Test crosses of "chocolate lilac" Jacob to both moorit and homozygous white are giving the same results...black lambs. (And in our case, piebald black and white lambs.)
    2) If different lilac colors are the result of different combinations of genes, then occasionally we should have some funky results from crossing lilac to lilac. Has any one seen this?

      Okay folks, here it is: http://members.aol.com/hobsickle/JacobSheepColorGenetics.html.  I've spent the last three months on this and perhaps it's ready to go--do what you all do best and pick it to pieces!  As it does not deal with Shetland genetics it will not answer some of the current questions, but I bet it will stimulate excessive dialogue.

      PS I should add that I feal like there is one piece of the puzzle missing yet.
