Colour+Blindness+In+One+Eye

Colour blindness is a condition where a person has a decreased abililty to see colour. This means there is a defect in the developement of one or more of the cones in a persons eye. People that have this condition are blind, they just see colours the average person would see in different hues with the exception of a few people not being able to see colours at all. Colour blindness is a condition that is passed through genes, and is more often in men because the photopigment is passed on through the X chromosome, because men only have one X chromosome, where women have two, which is often enough to pass on the pigment.

Colour blindess relates to the eyes and optics because it is a condition that effects the eye, and how a person sees.



Even though it is possible to be colour blind in one eye, it is very rare. Colour blindness in one eye would occur if during the development of an embro a mutation occured in the cell that passed on to one retina and not the other. This is an example of genetic mosaicism. It is also possible but super rare, that two embryos in primitive form could fuse together and one of the embryos had the colourblindess trait and passed it on, but the other one didn't. This is called genetic chimerism.
