3. Coat Color and Tail Length in Dogs In dogs, coat color and tail length are determined by two separate genes. Coat color is controlled by the B gene, where B represents the dominant allele for black coat color, and b represents the recessive allele for brown coat color. Tail length is controlled by the T gene, where T represents the dominant allele for long tails, and t represents the recessive allele for short tails. Parent 1 is heterozygous for both coat color (Bb) and tail length (Tt), exhibiting black coat color and long tail. Parent 2 is homozygous recessive for both traits (bb tt), displaying brown coat color and short tail. a. What are the possible gametes produced by each parent? b.
