It’s a real-world scenario about inheritance patterns in one of America’s favorite dog breeds. You may read about other coat variations, such as “silver,” but the AKC does not recognize this as “standard,” and silver Labradors cannot be shown at AKC-sanctioned events. One well-loved example of recessive epistasis is the coat color of Labrador retrievers.

My hypothesis was correct, because all the puppies that were born had a black coat. The Epistasis gene is a mutant gene that copies the dominant gene over and over again.
Coat colour in Labrador retrievers is a good example of this. The gene-by-gene inheritance pattern can also be called epistasis.
