[Jacob-list] question on horns

[Mary Hansson]

Fred,
 
I have observed a Cotswold/Jacob cross POLLED animal with a grade 4 split......shocked both me and the breeder.  Just another animal that messes with our great theories.
 
BTW:  The little 4-horned ram lamb that was born a couple months back to parents that were/are both 2-horned (at least on visible CLOSE inspection) is one of the prettiest ones in the flock of lambs---markings, horns, fleece, everything.......  Fleece isn't as good (fine) as Nutsy's fleece was, but it is nice.

I hope someone else will jump in here on this, as I may be wrong, but I think that since SUED is linked to the polycerate gene, you would most often (but maybe not always) see it on four horned animals.  Does sued occur in hornless and/or polled sheep? 

Split upper eyelid defect is associated with polyceraty and therer are no reports I am aware of that hint of such a defect in polled sheep.  As to the "hornless" phenotype the question should be placed on the table.  There are impediments to answering the question: the observation in the ewe of the sex-linked "hornless gene" presented as an aberrant horn and the scur at the lateral horn location, the willingness to present such a finding which would suggest other questions.
