A: The best way to identify potential tetrachromats is by looking at maternal male relatives. From our research so far, we know that the most likely candidates for tetrachromacy are those who carry the gene for very mild colour vision deficiency.
What does it mean if you have tetrachromacy?
Tetrachromacy is the condition of possessing four independent channels for conveying color information, or possessing four types of cone cellcone cellCone cells, or cones, are photoreceptor cells in the retinas of vertebrate eyes including the human eye. They respond differently to light of different wavelengths, and are thus responsible for color vision, and function best in relatively bright light, as opposed to rod cells, which work better in dim light.https://en.wikipedia.org › wiki › Cone_cellCone cell - Wikipedia in the eye. Organisms with tetrachromacy are called tetrachromats.
What color cones do tetrachromats have?
These cones are often referred to as blue, green and red cones depending on the particular wavelengths of light that trigger them into action. In comparison, tetrachromats are endowed with a fourth type of cone, which is most sensitive in the yellow-green region of the visible spectrum.
