color blind?

Question

do two color blind pepole see the same or do they each see diff like some see grey but others may see black so if tow were color blind would u both see the same color? and why is it only men can be color blind

Answer 1

Color blindness is a recessive X-linked allele....women have two X-chromosomes, men have only one X-chromosome

...so if a woman has one X-chromosome with color blindness and one without the allele, then she will still see color fine because it's a recessive gene

...men only have one X-chromosome and one Y-chromosome, so men only have one shot to get it right

I learned we see in 3 main color spectrum in the cones in our eyes...the chromosome for blue is not an X-linked genotype, but red and green are....so color blind people will see greens and reds differently

Answer 2

women can be, but it's a sex linked trait, making it much more likely for a recessive allele to be expressed on an x chromosome, because male's only have one.

that's not what colorblindness is.

most commonly it's red-green colorblindness, and they can't tell the difference between those two colors.

very few colorblind people are 100% colorblind, they just have trouble telling the difference between some colors. So it will vary, can 2 people with foreign accents understand each other? no cause accents will differ.
