How could you genetically modify an animal so that it would distinguish more shades of green?
A) Induce genes to produce a greater number of cone cells in the fovea.
B) Introduce genes for different opsins that respond in the green region of the spectrum.
C) Introduce genes to produce green fluid in the eyeball, because green fluids will not absorb green light.
D) Induce increased production of cGMP to increase opening of cGMP-gated sodium channels.

Introducing genes for different opsins that respond in the green region of the spectrum would allow for the animal to detect more shades of green. Opsins are the proteins that respond to light and are found in cone cells in the retina of the eye. By introducing opsins that are tuned to different wavelengths of light, the animal could distinguish a broader range of colors, including different shades of green.
