In guinea pigs, a black coat (B) is dominant over a white coat (b), and straight hair (S) is dominant over curly hair (s). The genes for coat color and type of hair are located on different chromosomes.  A heterozygous, black, and straight hair guinea pig (BbSs) was test crossed. A guinea pig heterozygous for both traits mated with a homozygous recessive guinea pig. What is the probability of having offspring with at least one dominant trait? Select one: a. 0.50 b. 0.00 c. 0.25 d. 0.75 e. 1.0
