RE: A journey into the world of optics: How are we able to see different objects and colors?
I think it's because the genes for the colour receptors are on the X chromosome. XX woman have two chances to get the genes, XY men only have one!
That's partially true, the two main genes for color vision are OPN1LW and OPN1MW.They are found on chromosome X and one can have more than one copy for the OPN1MW, but why i still ignore that ! Maybe two copies makes the activation of these genes more intense in women, i really don't know
