In horses, the coat color black is dominant (B) over chestnut (b). The trotting gait is dominant

(T) over the pacing gait (t). If a homozygous black pacer is mated to a homozygous chestnut,

heterozygous trotter, what will be the ratios for genotype and phenotype of the F1 generation?

Make sure to discover the genotypes of both parents before you begin making the punnett square. Also

remember to use the FOIL technique to figure out what goes on the outside of the square.
