If a female 100 percent Lab is mated with half Half Golden retriever mix and the resulting litter 8 puppies it possible for one of to be genetically Lab?

It's impossible for one of the puppies to be genetically 100% Lab in this scenario. Here's why:

* Genetics 101: Each parent contributes half of their genetic material to their offspring.

* The Dad's Genes: The father is a mix of Golden Retriever and something else (unknown). This means he carries a mix of Golden Retriever and other breed genes.

* The Mom's Genes: The mother is 100% Labrador.

* The Result: Since the father carries a mix of genes, every puppy will inherit at least some of those "other" genes, making them not purely Labrador.

Therefore, even though the mother is a purebred Labrador, none of the puppies can be 100% Labrador genetically. They will all inherit a mix of Labrador and Golden Retriever genes, as well as whatever other breed genes the father carried.
