This creates a visual result that some might call “super vision.” Tetrachromacy is a rare genetic phenomenon that is believed to only affect females. Up to 12% of women worldwide may be tetrachromatic. To a trichromat, they all looked the same, but Jordan hypothesised that a true tetrachromat would be able to tell them apart thanks to the extra subtlety afforded to her by her fourth cone. Incredibly, one of the women tested, cDa29, was able to differentiate the three different coloured circles in every single test.
By Alexa Tsoulis Reay. Tetrachromats can see colors that most people cannot — up to 100 million, estimates suggest, which is 100 times that of the average human. Most people have three cells, or receptors, in their retinas, but tetrachomats have a fourth receptor, which may be what allows for their heightened color perception.
The T-test is a statistical test that measures the significance of the difference between the means in two sets of data in relation to the variance of the data.Dec 1, 2019 · Tetrachromacy, a phenotype arising from X-linked genotypic variants, is an exciting prospect and it now seems likely that there are individuals who fit the expected profile. However, the relationship between the existence of a fourth class of retinal cone and the dimensionality of color vision is more complex than previously thought.
