Question

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. Color blind
• B. Night blind
• C. Blind in both eyes
• D. Blind in one eye

Answer 1

Answer: (A)

Color blind

The rods and the cones are the photoreceptor cells in the eyes. The rod cells are for the black and white vision while the cones are for the color identification. The baby is born with the rods and no cones in his eyes, which will result in the complete color blindness.

Thus, the correct answer is option A.
