Dihybrid Cross: In horses, black coat color is influenced by the dominant allele (B), and chestnut coat color is influenced by the recessive allele (b). Trotting gait is due to a dominant gene (T), pacing gait to the recessive allele (t). If a homozygous black trotter is crossed to a chestnut pacer,
i. what will be the appearance of the F1 and F2 generations?
ii. which phenotype will be the most common?
iii. which genotype will be the most common?
