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? **Make a Punnet square for help**(1 point) Responses BB BB Bb Bb BB and bb BB and bb bb
To determine the genotypes that would lead to a spotted phenotype in this dog breed, we need to consider the dominant and recessive alleles for coat color.
Let's create a Punnett square to help us understand the possible genotypes and phenotypes:
B B
________________
b | Bb Bb
b | Bb Bb
The Punnett square shows four possible genotypes: BB, Bb, Bb, and bb.
However, since the trait for a spotted coat is recessive (allele b), the only genotype that would lead to a spotted phenotype is bb. Therefore, the correct answer is "bb".
