Red Factor Charolais bull

So this year I have a pretty good red purebred charolais bull calf. I was asked to test him for the dilutor gene. He tested non-dilutor which Im told is good. Im not too familiar with the red gene in Charolais so I was wondering what this actually means in simple terms? Does it mean he will not break coat when he is bred to white charolais cows - in effect being homozygous red? TIA

It means that he is homzygous for the non diluter gene and he will only put out red carrier calves or darker red calves(homozygous) such as himself.  All charolais are red except for some black charolais that can either be hetro zygous black or homo black.  The diluter gene makes them white if they are homozygous for the diluter gene if they are heterozygous they are buckskin or grey.
So what is the brreding of this calf?  What is market as you see it?

Thanks Mark. I was hoping it meant he would not break coat. I just wasnt sure what this test proved. He is off an old red cow by Contender and the Fired Up bull. He will be in a purebred operation I'm sure.

If the ccow does not show any white particularly not above the belly line I don't think you have much to worry about. fired Up is solid colored and isn't related to some the known red bulls that throw white.  By the way to those looking at this post here is a picture of fired up: https://www.circlecee.com/popup/2015/104.htm
