Why are cows black white?

Answer 1

Holsteins are. But there are many other breeds and cross-breds that are not black and white, but instead can be all black, black with a white face, red, red with a white face, brown, yellow, tan, buckskin, blood red, orange, grey, mousy grey, etc.

Answer 2

They are different breeds of cows or the same breed with different colors. For instance, Holsteins can have a genetic mutation that enables the breed to produce brown-and-white Holsteins instead of the usual black-and-white ones. And, where Holsteins are black-and-white, other dairy breeds like Ayrshire and Guernsey are primarily brown-and-white.

Answer 3

They're just of different colourations.

In the Farmville game, however, white and brown or black cows can be sold for 6 coins. Brown cows for 12 coins and pink cows for 18 coins. Bulls are worth 80 coins.

Answer 4

It is actually down to genetics: DNA and the mutations that occur in DNA sequences that change protein structures and sequences and how such mutations can be maintained from one generation to another.

In all actuality, not all cows are black and white. Specific breeds are black and white such as the Holstein, the Istoben and Karan Fries. These breeds have been developed using a slightly more advanced understanding of Mendelian Genetics in order to create a pure breed that produces animals all of the same colouration--black and white, but not necessarily the same colour pattern (since this is impossible unless you clone a cow).

Also note that cows--being the mature female bovines--can be any colouration, colour pattern or colour. Not all cows are black and white, just like not all bulls are brown or black and have horns (That's Disney for you). Only those cows of a particular breed like those mentioned above are black and white, and the same with the aforementioned bulls. A mature female bovine that has given birth to a calf can be solid black, solid red, red and white, solid white, solid brown, brown with horns, grey, etc.

Here's another fun fact: All Holstein cows are horned. They have just been disbudded when they were tiny calves. If they were not disbudded (or "dehorned" to some), then those cows would all be black and white with horns.

Answer 5

It is like blondes and brunettes, they have different genes and stem from different places originally. I wonder if most bulls prefer the white cows sexually?
