Color blindness is a condition in which the red-sensitive nerves in the eye fail to respond to light properly. This condition is also known as color vision deficiency. It affects a significant percentage of the population of the world. Blindness does not literally translate to an actual blindness but rather refers to just a deficiency of color vision. People who have this condition usually obtained or took this trait directly from their parents through genetic codes embedded within the cells during reproduction.<span> </span></span>
None of them are likely to express the recessive trait because they all have a dominate allele in their genotype. 2 of them will be homozygous dominant, but two of them will be heterozygous and carriers for the disease.
