Do you have relatives that are color blind?!


Question: Both of my brothers are color blind. My Maternal Grandfather was color blind. All my maternal male cousins are color blind. Does this run in your family? My Brothers had to learn to identify which light at a stop light was which color- by watching what light lit up was Stop-Yield-Go. My Brother's wife has to match his clothing for him.
Is anybody in your Family color blind? What makes this happen? I feel badly for the guys in my family, as they have no idea what true colors look like. I know it has to do with genetics, but, don't understand the concept of this. Do you?
Thanks to all who answer. I give all answers a thumbs up.

Color blindness is passed on to the MEN in ones family by their MOTHERS!

My brother is totally color blind. HOW he got into the Navy back in the 60's is beyond me!

When my son was in school, and able to identify all the colors correctly I breathed a sigh of relief! I just pray he doesn't pass the defective gene onto his own kids. They would not experience color blindness, but the daughters SON could.

It is the pits to have I am sure.
My own brother has always said he could see colors, however with the DOT test, he could see NOTHING!

Additional: I have to say the laser treatment for colorblindness, if such a thing would fix this problem, many would have it done. It is caused by a missing GENE. Nothing can fix that...

Yes, my second cousin Sean is color blind. He went and got that whole laser thing done and now he just has to put in eye drops and he can see in color now, it's pretty cool!

And my best friend's dad and little brother are both color blind.

I recently found out my Father-In-Law is color blind. No one else on my husbands side as far as I understand. Also, my father (who did not raise me) is color blind. I'm a female and I'm not. That's strange how many men in your family have that condition. I don't believe that is genetically related. You could probably find the answer to that from a medical web side such as Web MD. Hope you can find the answers you are searching for. Also dry ask.com, start with something simple like "color blind" and let it guide you from their. Good luck!

My grandfather was and two of my male cousins

yes, my sisters husband is or was. He had a surgery done here while back & it was suppose to fix it.

He couldn't distinguish red lights from green light, & i dont know how he saw how to drive.

Many men are color blind. Both my sons are and my husband is as well. My dad is also color blind.

I asked the eye doctor, he told me many men are.

Colour vision defects are inherited as a sex linked recessive.

This means that the genes for colour detection are on the X chromosome and that a person needs a least one non defective gene to have normal colour vision. Women have two X chromosomes so they have two chances to get a normal gene. Men have only one X chromosome, they only get one chance.

If a man gets the colour defective gene, he will have a colour defect and pass that gene onto all of his daughters but none on his sons (men give a X chromosome to daughters and a Y chromosome to sons). If his wife gives a colour normal X chromosome to his daughters, then the daughters will have one normal X, one defective X. The daughters' sons will each have a 50/50 chance of getting the defective chromosome.

So the pattern in your family is the expected one. Your maternal grandfather's daughters sons (you, your brothers and your cousins) have a chance of being colour defective.
