According to genetics theory, red-green colorblindness in humans is a recessive sex-linked characteristic. In this case, the gene is carried on the X chromosome only. We will denote an X chromosome with the colorblindness gene by X and one without the gene by X . Women have two X chromo...

The term color vision refers to our ability to discriminate objects based on their color – in fact, humans can differentiate among millions of hues. However, over 8% of the population experiences an inherited deficiency in color discrimination. Actually, the majority of color-vision defects is ...
1.Red-green color blindness is also called Daltonism, after English chemist and physicist John Dalton. 天色盲也叫「顿症」,其得名于身患此症的英国化学与物理学家顿。 2.A similar deficiency accounts for the most common form of dichromatic color blindness in humans. 同样的缺陷导致了大多数常见的人...

“Little by little, we began to work out the genetics of color blindness in humans,” Jay Neitz says. “The most common thing that happens is that humans lose one gene on the X chromosome. We say it’s basically a back-mutation. Humans turn back into a squirrel monkey.” It was full...
Though there is no cure for any kind of color blindness, there may be a more permanent treatment one day. Gene therapy has cured red–green color blindness in monkeys, and perhaps someday there will be a cure for all types of color blindness in humans. ...
