Aberdeen Moderator Plus® Cattle

"Black Baldy" is a type of crossbred beef cattle produced by crossing Hereford cattle with a solid black breed, such as Aberdeen Cattle-Angus, resulting in Black Miniature Hereford look alikes.

Cattle Genetics:

Black coat color is dominate over red coat color.

White face (Baldy) gene is dominate over solid colored face. As a result, calves will have some type of white markings (Baldy) on face. 

At Diamond WR Cattle we produce both black and red baldy colors due to our cattles' genetics. Many of our Aberdeen Angus cows carry 1-black coat gene and 1-red coat gene (heterozygous). The cows are black in color because the black gene (B) is dominate over the red gene (b) which is recessive. 

Black (B) is dominant to red (b) so red cattle must have two red (bb) alleles to have a red coat. 

Black cattle can either have two black (BB) alleles (homozygous) or can have a black and a red (Bb) allele (heterozygous). 

Punnett Square for coat color shows when mating a Hereford Bull (homozygous; red-bb) to Aberdeen Angus Cows (heterozygous; black & red-Bb).

Bb= Black Color Coat 50% of calves are black colored.

bb= Red Color Coat 50% of calves are red colored.
