Color blindness occurs when an individual is unable or has diminished ability to see certain colors. red‑green color blindness is an x‑linked recessive trait, and whether or not an individual is red-green color blind is influenced by three different alleles. xc codes for normal vision and is dominant to xcp and xcd. xcp is the protan type, which produces insensitivity to red light. xcd is the deutan type, which produces insensitivity to green light. however, heterozygous recessive individuals, who have the genotype xcpxcd, have normal vision. in a hypothetical scenario, a scientist evaluates 5000 males and 5000 females. of the males, 4601 had normal vision, whereas 399 were red‑green color blind. of the females, 4981 had normal vision, whereas 19 were red‑green color blind. when analyzed further, it was determined that 2 of the color blind females had the genotype xcpxcp, and 17 of the color blind females had the genotype xcdxcd. what is the genotype frequency of males with deutan‑type color blindness
