Consider the following scenario:

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?

In the scenario described, the allele B (black coat) is dominant, and the allele b (spotted coat) is recessive. For a dog to exhibit the spotted phenotype, it must have two copies of the recessive allele (bb).

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

bb

The statement that is true of all proteins is:

Their structure is related to their function.

This principle, known as the "structure-function relationship," indicates that the specific shape of a protein determines how it interacts with other molecules and performs its biological role.

The main benefit of genetic biodiversity is:

Genetic biodiversity helps populations adapt to environmental changes.

This increased variability in genetic traits within a population allows for a greater chance that some individuals will possess characteristics that enable them to survive and thrive in changing environments, thereby maintaining the overall health and sustainability of the population.
