In horses, black coat color is influenced by the dominant allele (B), and chestnut coat color by the

recessive allele (b). Trotting gait is due to a dominant gene (T), pacing gait to the recessive allele (t).
What color horse would you use to find out the genotype of a black trotter? Give the genotype and
phenotype. What will be an ideal response?
