I was having a discussion with a fellow Coop breeder, and we had a question about listing the color of our sheep on their registration papers. I have been...
Hi Martha, I am not sure about the rules of your registry but perhaps Marcia Adams would know if by Coop, you mean Coopworth. The genetics behind the color...
I just did some 'research' into the way white sheep associations (in the US) register their colored animals. As Martha says, each association needs to...
Does anyone know anything about the genetics concerning the red color in Tunis lambs? Is it heritable - and maintainable in crossbreds? Thanks for any help....
I do not have Tunis but once in awhile I judge some of the wool. It is never "red", mostly white with little red fibers which I would call little kemps on the...
I am Anita Garza from Needville, Texas (south of Houston). I joined your group because of a shared interest in COLOR. I am Founder/Registrar of the Painted...
Welcome Anita! Sounds like your sheep will be an interesting flock to study color genetics wise. Hope we can help if you have any questions-- Lanette ... ...
For those on the list who aren't raising Shetlands and Icelandics, you might like to look at an article that D. P. Sponenberg kindly wrote for our newsletter,...
Great article, thanks! Now, does any of this actually apply to my Romeldales (or other fine wools), or am I still left in the dark to figure out our genetics? ...
Sue, I found a great article about CVM color genetics by Karen Eidman in the book, "Colored Sheep and Wool"-- Exploring their Beauty and Function, edited by...
Near as I can tell, Romeldales (and CVMs) pretty much have the usual variants of English breeds, plus Rambouillet/Merino. So, the usual white is Agouti white,...
I just made the time to read this article, and find a statement confusing: <<When dark brown sheep are mated together a few of the lambs can come out black,...
Hi Holly: This is in line with what I have found so far in working with what I think of dark brown in my Shetland flock. I think that the sheep that I have...
Linda writes: <<I think that the sheep that I have that are dark brown are actually AaAaBBBb with some modifier that makes them dark brown. My dark browns so...
Linda and Holly, Very interesting. I noted the same statement, Holly, and lack the experience to agree or, disagree. It seems I do hear this from other...
I have had a few dark brown Navajo-Churro sheep. I have not been successful in them producing dark brown offspring. In my flock they seem to be BBBb. They...
Hi Holly and Connie: I do see a difference in the eye rims, etc. on my dark browns when compared to a true black. As I said, it is just a hunch that they are...
I'm off for a week, so if this generates discussion, don't be surprised by my silence... I think there are dark browns, and then there are dark browns. The...
... Hi all, A simplified version of my theory about Dark Brown Shetlands works like this: BB = Black Pigment (dominant) Bb = Moorit (recessive) BD = Moorit...
Hi Carol: Thanks for the theory. I have printed it out and will keep it with my modified colour breeding materials. I will post breeding results from time to...
Carol writes: <<Dark brown = BB/BD and is the result of black and co-dominant moorit pigments within the same fiber. (Theresa Gygi has reported seeing this in...
Hi all, I don't remember if I posted what I've done to this list or not but here is a very brief synopsis: Using a 400x microscope, I did a "quick and dirty"...
... Holly, Thank you for retreiving this information. My original theory was based on the idea that the eumelanin pigment starts out as a brown pigment and ...
Why couldn't dark brown be a modification of the moorit gene? (terminology?) stephen ... From: Carol Kelly Date: Wed, 7 Jul 2004 07:40:27 -0700 (PDT) To:...
... Stephen, Yes, originally I thought dark brown was a modification of the moorit gene. But I am leaning toward the belief that at least one BB gene needs to...
... Folks, I just realized that I may have confused you by presenting two different, but similar theories about the genetics of dark brown in separate...
Hi Carol and Linda, I have been following the discussions of Dark Brown with some humour and interest. I guess I am a terrible skeptic and don't quite buy into...
Hi Kim: I think you are right to be skeptical :-). And I fully agree that the dark brown sheep in my flock could turn out to be modified moorits. The...
