A good question is whether the wild type red allele exists in Shorthorn. In Galloway, for instance, an animal that expresses wild type red will have a muzzle so dark that it appears black. The same coloration is seen in Red Angus. On cows, there will also be very dark hair around the muzzle and on the head and chest of males, especially during breeding season. I think most of us have seen these dark muzzles. I think the dark mulberry color of old fashioned roans is also an expression of wild type red alleles. No proof that I know of, just an opinion.

Great article.

Its obvious to pick on shorthorns for bw.

The cute head is another deal.

To me, they are like the runts of the litter.

It would be interesting to know from a development perspective why that happens in all animals.

Neoteny, domestication syndrome. I read a lot about this when I was studying the lineback color pattern. It also applies to white heifer disease.

"In a nutshell, we suggest that initial selection for tameness leads to reduction of neural-crest-derived tissues of behavioral relevance, via multiple preexisting genetic variants that affect neural crest cell numbers at the final sites, and that this neural crest hypofunction produces, as an unselected byproduct, the morphological changes in pigmentation, jaws, teeth, ears, etc. exhibited in the DS. "

/// Hey Dale remember the Black Nose Margie of Aldens? She was one the better ones that came along Dont remember if she was an Improver but she was very close to the original Shannon Margie who may also have had Galloway-and certainly began a line of Shorthorns that are least as relevant today as 45 plus years ago  O0

I recall hearing of her and probably saw her at the NAILE?  An Improver according to DigitalBeef.

Another Margie from the same family was also flushed a lot--AF SHANNON MARGIE 924.

924 was probably the most important well known one by far But i saw a Dividends impact x Black nose female in Texas that was a real sow around 1993 WAY AHEAD OF HER TIME O0

Torgerson's white with a black nose Pearl (sired by Clark) was long before that.  1975 I think.  She did a ton of winning.  We had an occasional black nosed Shorthorn back in the 60's.  Nothing new.
