What color puppy would you get if crossed a white German shepherd with brown and black shepherd?

It's impossible to say for sure what color a puppy would be if you crossed a white German Shepherd with a brown and black German Shepherd. Here's why:

* Genetics are complex: Dog coat color is determined by multiple genes, not just one. These genes interact in complicated ways.

* White German Shepherds: The "white" German Shepherd isn't actually a true white. It's a dilution of the usual black and tan colors, often with a recessive gene called "piebald" or "merle." This makes their coat look white but the genes for brown and black are still present.

* Brown and Black Shepherd: This dog carries genes for brown and black pigmentation.

Possible outcomes:

When you combine these factors, you could get puppies with a variety of coat colors, including:

* White: It's possible, but less likely, as the white German Shepherd will carry the recessive piebald gene, which would have to be inherited from both parents.

* Black: Possible, if the brown and black shepherd carries two copies of the black gene.

* Brown: Possible, if the brown and black shepherd carries two copies of the brown gene.

* Black and Tan: Possible, if the brown and black shepherd carries both black and brown genes, as well as the normal tan gene.

* White with Black or Brown Patches: Possible due to the combination of piebald and other pigmentation genes.

The only way to truly know what color puppies you'd get is to consult a veterinarian or a dog breeder who can help you understand the specific genetics of the parents.
