Was the first Blue Weimaraner, Cäsar von Gaiberg the product of a cross breeding or of a spontaneous genetic mutation? In order to answer this question, German scientist at Ruhr-University studied the DNA of 24 Blue Weimaraners and one Gray Weimaraner from two Blue parents. They also looked at 20 unrelated Grays. Most of these… Read more about Blue Weimaraner Genetics Study
The crux of the “Blue debate” seems to lie on whether or not Cäsar von Gaiberg, the progenitor of the Blue Weimaraner was a cross-bred dog or not. There are three basic theories on how the Blue gene came into being in the Weimaraner: “The Doberman Cross Theory,” “Blues Always Existed Theory,” and “The Genetic… Read more about How Did the Blue Gene Get Introduced Into Weimaraners?
While there are many loci and alleles involved in the Weimaraner’s coat color, there are only two loci that are important for the Blue versus Gray coat color in the Weimaraner, the Locus B pair and Locus D pair. The B genes work in pairs, with one of each of these two alleles inherited from… Read more about Weimaraner Coat Color Genetics
