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 phenotypes?

bb

Bb

BB

BB and bb

Answer 1

In the given scenario, the allele "B" for a black coat is dominant, and the allele "b" for a spotted coat is recessive.

For a dog to exhibit a spotted phenotype, it must inherit two recessive alleles, meaning it must have the genotype "bb."

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

bb
