which of the following statements is true regarding individuals that have colour deficiency?
people with colour deficiency are tetrachromatic
colour deficiency affects only men
colour deficient individuals see some colours, but not as many as people with trichromatic vision
people who are colour deficient view the world in various shades of grey because of ambiguous signals from the cones in the retina

Explanation:

• Tetrachromatic people have four types of color - sensing cones, while color - deficient people do not. So the statement "People with colour deficiency are tetrachromatic" is false.
• Colour deficiency is more common in men due to the X - linked inheritance pattern, but it can also affect women. So "Colour deficiency affects only men" is false.
• Colour - deficient individuals have a reduced ability to distinguish colors compared to trichromatic (normal color - vision) people. They can still see some colors.
• Only a very rare type of color deficiency (achromatopsia) causes people to see in shades of grey. Most color - deficient people can see some colors.

Answer:

Colour deficient individuals see some colours, but not as many as people with trichromatic vision.
