    A dog breeder has a white long haired female dog. She knows that the genotype of this dog is bbhh. She wants to find out the genotype of a black, short haired male dog of the same breed. The two dogs are not related. She crosses the two dogs.
    i) Write down all the genotypes that can give the phenotype black with short hair.
    ii) Use genetic diagrams to predict which puppies will be produced if a black short-haired male of each possible genotype was mated with a white, long-haired female dog.
    iii) How could the dog breeder find out if the black short-haired dog was true breeding (homozygous) for both characteristics?
    I've managed to do the first two parts of the question but I'm at a loss for the last part. Could anyone enlighten me please?

    Doesn't matter now. I've figured it out.
