How to Become Tetrachromatic?

Women inherit two X chromosomes, so if a mutation occurs on both chromosomes, they have the potential of being a tetrachromat. As men only inherit one X chromosome, any mutations that occur would result in them having anomalous trichromacy.

How do you get Tetrachromacy?

The tetrachromacy mutation is only passed through the X chromosome. Women get two X chromosomes, one from their mother (XX) and one from their father (XY). They're more likely to inherit the necessary gene mutation from both X chromosomes. Men only get one X chromosome.

How do I know if I'm Tetrachromatic?

If you see between 20 and 32 colors, you have three types of color receptors. About 50 percent of the population are trichromats. If you see between 33 and 39 colors, you are a tetrachromat and have four types of cones.
