I have Dun cattle---want to breed dun cattle. If I am doing a color test to make sure I won't get red do I test for red or dun--or do I have to test for both? Does that make sense??

Rhonda, don't know what animals you have, so here's the full meal deal: You could have duns that are homo black or hetero black and either of the reds, and you'd still get dun. Both reds override dun. So, if you want just dun, I'd test for red and get rid of any that carry it. Otherwise, eventually you'll end up with offspring down the line that carry red on both sides of the pedigree, and oops, a chance for a red animal. If you have black animals, they'd have to be tested for both red and dun, unless you know for sure that one of the parents was dun and then you could count on the animal having one dun gene, and hopefully passing it on, so only have to test for red. clear as mud? ;D c.

Had a dun heifer born to a red dam and black sire. In order to register her as dun, she had to be color tested.
First set of results came back "b/b" (with a comment "Dun or Red animal, additional red test needed to determine color").
Second set of results came back "ED/E+ b/b (with the comment "Dun animal, carries Red").
Total cost: $60 The heifer had already been sold, but we didn't want the buyer to have any problems with the registry. Unfortunately, I am no color expert but I think the form should indicate the possibility of a retest at additional cost, and it did not. Oh well, lesson learned.

Hi gale, it's the pits getting things accurate, isn't it. Next time, if you think it's dun, have the animal tested for red instead. If there is a black gene in there, then it has to be dun, and you will be done. if the result comes back E+E+ or ee or E+e, then she can't be dun. By testing just the base locus, you'd have had the answer to her dun status by default. The registrar can't quibble that you didn't test for dun because dun only gets expressed if homo, AND there is at least one black gene. c.

Hi Carol, yes, that's what I figured...should have tested for red on the first go-round. Eh, what do I know? The heifer was dun so that's what I tested for. Live and learn. Thanks!!!

Gene, in this case she already had a not-black animal, and doing just the red test would be enough to determine the correct color for registration, which is what Gale was after.
We all know you are sold on Legacy, and that there is a financial saving by going through Judy. I don't want to set off another debate, but for those who haven't read the several other threads on the topic, testing through Judy sends the results to Judy. For some, loss of confidentiality and control over the results might justify the cost of testing with Davis direct and paying the extra $5 fee per test for the transfer of results to the assn accredited lab (TAM), or simply using TAM in the first place. c.

Why would any one care if Judy sees the results or not. Most would have the color info entered into the pedigree for everyone to see and for those who are not why would any one care if someone knew the color of there dexters.
