In Labrador retrievers fur color is controlled by two genes. One gene controls pigment production with the dominant B allele producing a black pigmentation and the recessive b allele a brown pigmentation. The other gene controls the deposition of the pigment in the hair with the dominant E allele producing a functional transport system and the recessive e allele a nonfunctional transport system. Which of the following genotypes belongs to a true-breeding brown lab, i.e. a lab that produces nothing but brown offspring when bred with another lab of the same genotype?   Choose an answer below: B/b, e/e b/b, E/e b/b, e/e B/B, e/e none of the above
