1.	A baby is born with the normal number and distribution of rods, but no cones in his eyes. We would expect that the baby would be – (A) colour blind (B) night blind (C) blind in both eyes (D) blind in one eye
Answer» Correct option (A) colour blind Explanation: Absence of cone cells in eyes is known as total colour blondness or monochromacy. This person views everything as if it were an a black and white television. Monochromacy occurs when 2 or all 3 of cone pigments are missing and color and lightness vision is reduced to one dimension.
