what is the genotype of a roan cow
The roan pattern, common is Shorthorn cattle, is inherited as a heterozygous genotype. Roaning is basically the intermixing of two different colored hairs-black and white make a blue roan while red and white make a red roan.In cattle with spots the roan only shows up in the area where the solid color would be-thus getting a totally blue cow is relatively unusual.oaning is basically the intermixing of two different colored hairs-black and white make a blue roan while red and white make a red roan.
