Genetics X-linked recessive question. Please help.?

In human beings, a recessive X-linked mutation, g, causes green-defective color vision; the wild type allele, G, causes normal color vision. A man (a) and a woman (b), both have normal vision, have three children, all married to people with normal vision: a color defective son (c), who has a daughter with normal vision(f); a daughter with normal vision (d), who has one color-defective son (g) and two normal sons (i). Give the most likely genotypes for the individuals (a to i) in this family.
