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 hel p^ (1 point)

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? Make a Punnet square for hel p^ (1 point)

OBB

O Bb

BB and bb

O bb

Answer 1

To create a Punnett square for this scenario, let's assume that "O" represents the genotype for a dog with an unknown coat color.

The possible genotypes that would lead to a spotted phenotype are:
- O Bb
- O bb

Here is the Punnett square for these genotypes:

| B | b |
---------------------------
O | O B | O b |
---------------------------
O | O B | O b |

As you can see, in both cases, there is a 50% chance of producing a dog with a spotted phenotype.
