Correct answer: A. Protanopia
- A. Protanopia
- B. Deuteranopia
- C. Tritanopia

Explanation
Protanopia is a type of color blindness that is caused by a mutation in the gene that codes for the L-cone photoreceptors. The L-cones are responsible for detecting red light, so people with protanopia cannot see red at all. They may see other colors as shades of yellow, orange, or brown. Protanopia is the most severe form of red-green color blindness.

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.
