How do you get the disease of color blindness?

Answer 1

You do not get color blindness, you are either born with it or not born with it. It is on the X chromosome. A male has one X chromosome. A woman has 2 X chromosomes. If one X chromosome does not have red-green capability and the man has that chromosome, then he is color blind. A woman can have one color blind chromosome and one non-color blind chromosome and she will not be color blind. The ability to see blue and yellow is on chromosome number 7. Everyone has two of those. A man can only have 3 color chromosomes. Women can have 4 color chromosomes. Since the chromosomes can be slightly different, women can frequently see far more color variations than men can see.

Answer 2

Color blindness can be spread hereditarily. You cannot "catch it" as it seems you are putting forth, it is something you are born with. Men are more likely to be color blind than women, and it is caused by certain cones in the eye not functioning properly.

Answer 3

It is a genentic mutation that comes form genes that you get from your parents.

It is usually the reccessive gene so there is a very little chance someone can get it
