A person suffering from blue cone monochromacy (BCM) will be:
Correct answer: D. Red and Green blind
- A. Red blind
- B. Green blind
- C. Blue blind
- D. Red and Green blind
Explanation
Blue cone monochromacy is a rare form of color blindness where the blue cone photoreceptors are dysfunctional, leading to reliance on only rod and blue cone cells for vision. This results in difficulty distinguishing red and green colors, hence the correct answer is 'Red and Green blind'. The other options are incorrect as they refer to specific types of color blindness (protanopia and deuteranopia), which do not apply to blue cone monochromacy.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
