tigerstripes & brindles dilutor gene

[gertman]

Evening,
Do tigerstripes and brindle colored cattle have the dilutor gene? The reason I ask is that I have 2 cows (one in the spring and one last month) that have had red calves sired by my registered black angus bull. I thought only Charolais, shorthorn, and some simmental had the dilutor gene.

It's red on the bull side and red on the cow side. A other case of an Angus bull not being homozygous black.

Bingo

Dilute gene is separate from black and red gene.
Totally agree with others. Your bull is Heterozygous black, meaning he is carrying 1 red gene and 1 black gene.

So what you all are basically saying is my registered black angus is a red carrier.

Definitely. Nothing else is possible. But it's not rare for a registered black Angus to have a red gene. Most other breeds test bulls for being homozygous black but I have not seen it tested in Angus .

yup. red carrier. oughta be able to look at his pedigree at AAA site andfind a known red carrier back behind him.


For a really nice overview of inheritance of coat color & patterns, Double Helix Ranch (TX Longhorns) has as good as I've seen recently - a 5-part series, with nice color photos of most colors, shades, patterns
