What color puppy will you get if breed a black lab with yellow lab?

You can't predict the exact color of a puppy born from a black Lab and a yellow Lab. Here's why:

* Genetics: The color of a Labrador Retriever is determined by two genes: the "B" gene and the "E" gene.

* B Gene: This gene controls the amount of black pigment (eumelanin). A dog with two copies of the "B" gene (BB) will be black. A dog with one copy of the "B" gene (Bb) will also be black. A dog with two copies of the "b" gene (bb) will be chocolate.

* E Gene: This gene controls the distribution of pigment. A dog with two copies of the "E" gene (EE) or one copy of the "E" gene (Ee) will have a normal distribution of pigment. A dog with two copies of the "e" gene (ee) will have a restricted distribution of pigment, leading to yellow fur.

* Combinations: A black Lab can be BBEE, BbEE, or BbEe. A yellow Lab can be bbee. Therefore, the puppies could inherit different combinations of these genes, resulting in black, chocolate, or yellow puppies.

Here are some possible outcomes:

* Black: If the puppies inherit at least one "B" gene and at least one "E" gene.

* Chocolate: If the puppies inherit two "b" genes and at least one "E" gene.

* Yellow: If the puppies inherit two "b" genes and two "e" genes.

It's a matter of chance! The exact color of the puppies will depend on which genes they inherit from their parents.
