Correct answer: C. Tritanopia
- A. Protanopia
- B. Deuteranopia
- C. Tritanopia
- D. Protanomaly
Explanation
Blue blindness is called tritanopia. It is a rare form of color blindness that is caused by a mutation in the gene that codes for the blue cone photoreceptors. People with tritanopia have difficulty distinguishing between blue and green, and they may see other colors as shades of blue. Tritanopia is much less common than red-green color blindness, and it is usually inherited in an autosomal recessive manner. This means that both parents must carry the mutated gene in order for their child to be affected.

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.
