You are referring to the Holstein breed which most milk comes from. The white pattern is for normal milk. The black pattern can be mixed with the white pattern to produce chocolate milk.

So that when they escape from their field, they can hide, unseen, on a checkers board...... The Bigyin

cows come in a variety of colours not just black and white, depending on the breed.

Because they were bred that way in Europe.

well if zebras have black and white strips to confuse their prey or predator, or something like that, i would imagine that it would be the same for cows. i think.

How do you know that it's not a white and black pattern ?

Those cows are called, Holstien Cows. Just another beautiful breed of cows. I love'em all! You will find them on most dairy farms and they supply our "store bought" milk.

To answer your question: The patterns are determined by genetics; but not all bovine quadrupeds are black and white. Some are all black, some brown, some are almost orange, some are off white. There are as many breeds of cattle as there are cats or dogs. This website may help: http://www.animalgenome.org/

Because they would look really weird if they were green and pink patterns.

OH MY, your not from the country I am guessing? So many different cows there be, and many different colors, and patterns. from the solid jet black of the lady Angus, to the white face upon the woman who is the Bovine Diva "Hereford!" Now, those two are NOT Dairy Cows, as their milk is too low in butterfat, and isn’t as tasty to the human palate as those I’ve listed for ya. Angie, and Herfie are used mainly as "breeders" to give the daddy Bull some afternoon delights, and thus the propagation needed to provide for us, the two main sources or our edible beef products, as well as the leather for our apparel. NOW, your "Holstein" or Black and White is probably the most abundant "MILKING" Cow, as they produce about double, pound for pound than any other, but for richness in butter fat, nothing beats the Guernsey. I have made you a little cow chart from the pictures on the Purina site, and also if you "CLICK BELOW, YOU CAN PURCHASE A PURINA MILLS DAIRY BREED POSTER TOO!: http://dairy.purinamills.com/poster.html I hope this was a fun little trip to bovine 101! Be well, and Peace!

It is DNA that does the color determining. Although some breeds have been bred and selected for their color patterns, it is still the dna, just like your hair being blond, brunette, etc...
