Which factor best explains why it is possible to have a genetic disorder causing a difficulty that is limited to distinguishing two particular colors?
A) Sensory processes are sensitive to interactions among chromosomes.
B) Sensory abnormalities are difficult to detect in prenatal testing.
C) Sensory cells produce specialized proteins for specific purposes.
D) Sensory deficits more commonly result from the presence of recessive alleles than from the presence of dominant alleles.

Question

Quizplus · Accepted Answer

Sensory cells in the eyes produce specialized proteins called opsins, which help distinguish colors. Different opsins respond to specific wavelengths of light, which allows humans to perceive a range of colors. Genetic disorders can disrupt the production or function of these opsins, leading to difficulties in distinguishing particular colors. This is possible because each color is perceived through a different set of opsins, so a disorder affecting only one or a few opsins can cause difficulty distinguishing specific colors.
