Organization of the human trichromatic cone mosaic. Mammals mostly lost the ability during their early evolution, when our mammal ancestors transitioned from being nocturnal to diurnal. The normal explanation of tetrachromacy is that the organisms 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. The Humans With Super Human Vision | Discover Magazine You see between 33 and 39 colors: you are a tetrachromat, like bees, and have 4 types of cones (in the purple/blue, green, red plus yellow area). These alleles often have a different spectral sensitivity, so if the carrier expresses both opsin alleles, they may exhibit tetrachromacy. Greenwood V.

The other likely carries regular L genes as well as mutated L gene passed through a father or son with anomalous trichromacy.
