Question

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 exact genotype of a black trotter? Explain.

Answer 1

Bb or BB and Tt or TT

Step-by-step explanation:

Black coat could be BB or Bb because it only needs one dominant allele for the trait to show up and the same goes for Tt and TT.
