FAQs on A colour blindness problem - NEET
| 1. What is colour blindness? |  |
Ans. Colour blindness, also known as color vision deficiency, is a condition where an individual is unable to perceive or distinguish certain colors or shades. This occurs due to a defect or absence of certain cells in the retina that are responsible for detecting and interpreting colors.
| 2. How common is colour blindness? | |
Ans. Colour blindness is quite common, affecting approximately 1 in 12 men and 1 in 200 women worldwide. It is more prevalent in males because the genes responsible for color vision deficiency are carried on the X chromosome, and males only have one X chromosome.
| 3. Can colour blindness be inherited? | |
Ans. Yes, colour blindness is often inherited. It is mainly passed down through the X chromosome, which means it is more commonly inherited from the mother. However, it can also occur due to certain genetic mutations or as a result of damage to the retina or optic nerve.
| 4. What are the different types of colour blindness? | |
Ans. There are several types of colour blindness, including red-green color blindness, blue-yellow color blindness, and total color blindness (achromatopsia). Red-green color blindness is the most common type, where individuals have difficulty distinguishing between shades of red and green.
| 5. Can colour blindness affect daily life and career choices? | |
Ans. Yes, colour blindness can have an impact on daily life and career choices. It may make it challenging to distinguish traffic lights, read maps or charts, and identify certain objects or signs. In terms of career choices, certain professions such as pilots, electricians, and designers may require normal color vision. However, many individuals with color vision deficiency lead successful and fulfilling lives in various fields.
