Question 1:
What is the most common type of color vision deficiency?
Explanation: The correct answer is B) Deuteranomaly. Deuteranomaly is the most common type of color vision deficiency, also known as red-green color blindness. Individuals with deuteranomaly have difficulty distinguishing between shades of red and green due to a defect in the medium-wavelength cones (M cones) in the retina.
Question 2:
Which type of color vision deficiency is characterized by a reduced sensitivity to blue light?
Explanation: The correct answer is C) Tritanomaly. Tritanomaly is a type of color vision deficiency characterized by a reduced sensitivity to blue light. Individuals with tritanomaly may have difficulty distinguishing between shades of blue and green, and may perceive blue colors as more greenish or yellowish.
Question 3:
What is the term used to describe complete color blindness?
Explanation: The correct answer is D) Monochromacy. Monochromacy, also known as complete color blindness, is a rare condition in which an individual lacks functioning cone cells in the retina. People with monochromacy see the world in shades of gray and may have reduced visual acuity.
Question 4:
Which color vision deficiency affects the perception of all colors as shades of gray?
Explanation: The correct answer is D) Monochromacy. Monochromacy, or complete color blindness, is a condition in which an individual sees the world in shades of gray. It is characterized by the absence of functioning cone cells in the retina, leading to a lack of color perception.
Question 5:
Color visiondeficiencies are more common in which gender?
Explanation: The correct answer is A) Males. Color vision deficiencies, particularly red-green color blindness, are more common in males. This is because the genes responsible for color vision are located on the X chromosome, and males only have one X chromosome. Females have two X chromosomes, which reduces the likelihood of inheriting color vision deficiencies.
