From: Will Kuipers Re: Color Blindness and PD The question has come up: how prevalent is the presence of color blindness in PWP. For those interested, I am color blind ( very moderately ) in the red-green dominance field. Where normally people see red as dominant over green, this situation is reversed in my case. I have known this since 1939. It has been established that this is associated with a gene that is passed on through the female gender. I can't see the connection with PD as being quite tenuous.
