Consider the following scenario:

Question

In a certain dog breed, the allele B for a black coat is dominant, and the allele b for a spotted coat is recessive. What genotypes for this dog breed would lead to a spotted phenotype?
(1 point)
bb
BB
BB and bb
Bb

Answer 1

The genotype that would lead to a spotted phenotype in this dog breed is bb. This is because the allele for a spotted coat (b) is recessive, meaning that an individual must have two copies of the recessive allele (bb) to express the spotted phenotype.

In summary, the answer is bb.
