colorblind

[insename2]

hey, i searched a lot for this and can't find it, is there a way to test the parents to see if their offspring will be colorblind... a source would be useful... thx

Well, a sufficient sample of offsping would do it...then you could statistically tell if they'd have colorblind children, but you'd need tens of thousands of offspring to be sure 😛

That could be a fun experiment.

They had some good songs in the 90's, but I don't think they're colorblind.

well, i guess, but is there a way via DNA sampling and the such?

Isn't there a gene responsible for it? If so, it ought to be possible to test for it in the parents and work out the probability of their child having it...

 

[imported_LoKe]

The gene is in the mother, I believe.

yea, its in the X chromosome, i just havent heard of testing it yet... can it be tested?

 

[hjo3]

The gene for red-green color blindness is transmitted from a color blind male to all his daughters who are heterozygote carriers and are perceptually unaffected. In turn, a carrier woman passes on a mutated X chromosome region to only half her male offspring. The sons of an affected male will not inherit the trait, since they receive his Y chromosome and not his (defective) X chromosome.

being color deficient sucks, a whole lotta a--
🙁

http://www.agape1.com/color%20vision.htm

best page i've ever seen on the problem
my mom is not only a carrier, but actually is color deficient herself... so i was guaranteed to be color blind 🙁
wonder if my when my older sister has kids, if they will have it.. my sister is guaranteed to be a carrier, so she has a 50/50 chance of having a colorblind boy if she has a boy, and a 50/50 chance her daughter will be a carrier
i hope her kids are both not afflicted in any way, would be nice to help get this thing wiped out of at least her side of the family ... any girls i have are guaranteed to be carriers 🙁

i can't make out any of the numbers in the colored dots in this page

do color blind people have to obey traffic lights?

 

[Maximus96]

i was told i am red-green color blind, as post above i can not make out the numbers in the dots. but oddly enough i can clearly tell the 3 colors in the traffic lights.

Probably, but as DaTT pointed out, that wouldn't be as fun 😀

on most traffic signals around here in toledo, the red is vibrant red so i see it. the yellow is a vibrant yellow to me as well, but the green. oh, i was poked fun at by some friends when i had to be told the green light is really green (this was a couple years ago). I was like 'why do they call it a green light when its just white'... needless to say, they got a laugh out of it lmao
i did too, cuz well i know im color blind, just it really is interesting to find out how things really look like to others

its no accurate analogy, but its similar to blind people who finally can see after some surgery or something. or more accurately, its like a blind person being told what its like to see. for me, i like being told what its like to see the colors that i apparently dont see.

im red/green colorblind too.. thats the most common, having the blue rod/cone effected is rarer than red/green.
its funny when people ask me though, whats it like to not see color. im like, i can see color. just not every shade. and then the tests of 'what color is my shirt' and 'what color is this' and that, and this, and that... lol some people are really thick, i've learned
im not sure how others are, but for me, i can see vibrant shades... like, what would be considered pure pink, red, orange, purple, blue, cyan, green, brown, yellow, grey... etc etc etc, i can see just fine.. but throw in those damned green lights, that are not a vibrant green, i cant see it... i dunno, i consider the 'pure' shades to be ones i can see, cuz i can obviously see them so there must be something about them that makes me able to see them.

it would be great for some kind of gene therapy to fix the afflicted gene so us color blinds are no longer colorblind, and more specifically rid the gene from our body so we cannot pass it on.
