Yes
By breeding the dog with another dog whose phenotype is already known
See the link
to simply kill 1 of the beans and see how it determine the phenotype works then you do it your self and there is your answer.
(In genetics, the phenotype is when genes combine to determine dominant traits.) "Researchers studied the phenotype of the mutated rats."
You can see them in it's feces.
Phenotype
If u want to know what a dog is, its that thing u see with the brown fur walking down the street with a leash. The way u can tell a dog is a dog is that they have long ears (usaully) and they have a brown ugly poo
you cant know for sure by looking at a dog. But you might see unusual actions
The genotype of an organism refers to its genetic makeup, while its phenotype relates to its observable traits. For example, a plant with the genotype for tall height may exhibit a phenotype of actually being tall in stature.
A very easy way to remember these two terms is: phenotype is what you see and genotype is what is in the genes. You may have B blood type (what to see) but you could have BB or BO (what is in your genes.
Vets can usually test a dog's blood to see if the dog has had a certain shot.
I don't know. I can't see over my extremely large gut.
