I was very happy with polled results. I have a question about the color results, black is dominant, but if a cow or bull carries red and dun, can they pass either color to an offspring? Or will a black animal always pass the black gene. Ed/e+Bb I am new to figuring this out.

Hi Pinevalley, If a cow/bull carries red and/or dun, they have the potential to produce those colors. The animal must be bred to another animal which carries or is red and/or dun. in order to produce those colors. John Potter, a very knowledgeable breeder, put together some very informative info on color genetics. Check out the link below. Congrats on your results! www.sprucegrovefarm.com/dextercolorgenetics.htmEileen

Thanks I have heard of John Potter, and I believe I have a cow that has one of his bulls in her heritage. Cathy

So if a two year old cow has no horns then he or she is considered polled?
I though it was a trait that had to be bred into the animals.
Continuing education.

Windswepthill, as long as the two-year old was not de-horned, yes, it is polled. And yes, the trait came from its breeding. Polled is a dominant trait over horned, so (to make things simple) . . . if you breed a horned animal (it has to have two horned genes to be horned) with a polled animal that has two polled genes (called "homozygous polled"), the calf will get one horned gene from the horned parent and one polled gene from the polled parent, and it will be polled but it will carry a horned gene (called "heterozygous polled"). It gets more complicated and less easy to tell what you'll get when you breed two heterozygous animals. The ADCA has an article about it on the website. Here's an article from Gabriella Nanci of Belle Fourche Dexters. Hope that helps. It can get confusing! With cattle, the education is always continuing!
