Answer 1

In the given scenario, the allele B (black coat) is dominant, and the allele b (spotted coat) is recessive. For a dog to have a spotted phenotype, it must express the recessive trait, which means it must have two recessive alleles (bb).

Therefore, the only genotype that would lead to a spotted phenotype is:

**bb**.
