41. Using the provided graph, match the human digestive enzymes with their optimum pH. 

29. Eye pigment in a particular strain of fly is determined by two genes. An autosomal gene that controls the color of the pigments in the eye has two alleles: a dominant allele (R) that results in red eyes and a recessive allele (r) that results in sepia eyes. A sex-linked gene that controls the expression of the colored pigments also has two alleles: a dominant allele (T) that allows for expression of the colored pigments and a recessive allele (t) that does not allow for expression of the colored pigments. Individuals without a T allele will have white eyes regardless of the allele of other eye color genes. Which of the following represents a cross between a white-eyed female and a red-eyed male?
