Answer:
In horses, black coat color is determined by a dominant allele B and brown coat color by its recessive allele b. The trotting gait is due to the dominant allele T and the pacing gait is due to its recessive allele t. If a homozygous black/pacer is mated to a homozygous brown/trotter, what will be the genotypes and phenotypes of the offspring .
BBtt X bbTT= BbTt, BbTt, BbTt, BbTt
Explanation:
The genotype of the offspring Heterozygous Black trotting gait while the phenotype is all Black trotting gait.
