An even fewer percentage can make use of them properly. Do NOT follow this link or you will be banned from the site! A woman, who has two X chromosomes, can carry the normal red and green genes on one of her X chromosomes and an anomalous gene on her other one. These genes are very similar and are prone to errors during early development of a foetus. Organisms with pentachromacy are termed pentachromats. [4], The normal explanation of tetrachromacy is that the organism's retina contains four types of higher-intensity light receptors (called cone cells in vertebrates as opposed to rod cells, which are lower-intensity light receptors) with different spectral sensitivity. [3] The common ancestor of all vertebrates was a tetrachromat, but mammals evolved dichromacy, due to the nocturnal bottleneck, losing two of their four cones. 25% of the population is tetrachromat., According to the article, this could explain why people see the dress differently.

However, for her to be a true (strong) pentachromat, these opsins would need to be segregated into different photoreceptor cells and she would need to have the appropriate post-receptoral mechanisms to handle 5 opponent process channels, which is contentious. Derval says the number of colors you see depends on the number and distribution of cones, or color receptors, in your eyes. Trichromats make up half the population.
