What cause of the color blindness?

Answer 1

Colorblindneess does not progress over time. You are either born with it or you are not. It is in your genes to be color blind. Colorblindness is a recessive gene so it skips many generations but sometimes people are born with it, obviously.

Answer 2

Usually its genetics but it usually is dominant in males than in females so say your great- great grandfather was color blind and then the next generation if the only male isn't color blind it is possible that the anyone in that line could be a carrier of that genetics and someone in the next generation will get it

Although some forms of ocular pathology can result in disturbance of color vision, as can some changes associated with aging, nearly all color deficiency of significant degree is hereditary, congenital (you're born with it), and permanent.

The most common forms of congenital defective color vision, the red-green deficiencies, are due to "sex-linked X chromosomes" and "simple recessive hereditary traits". Men are mainly affected because women have two X chromosomes and men have only one X and a Y chromosome. If a man's one X chromosome is color defective he will be color deficient, where as, a woman must inherit two color defective X chromosomes to be color deficient. For a woman to be color deficient, her father must be colorblind and her mother colorblind or be a carrier. All possible patterns of inheritance of any one of these color defects are shown here:

A color-defective male always inherits his deficiency from his mother, who usually has normal color vision and is therefore a carrier of the defect. She may have received her color-deficiency gene from either her father (but only if he was color defective), or from her mother (who could have been a carrier herself, or rarely, who was color-defective).

Another color deficiency "blue-yellow defect" also exists, but need not be discussed here because of its comparative rarity and lack of commonly available tests for blue-yellow abnormalities.

Answer 3

Absence of a sex linked gene causes color blindness.To produce cone cells which are must to detect colors, all need a dominating x-linked gene. When the dominating gene is absent ,one become color blind from the birth. Women are the carrier of it, but men are the Vitim's. Color blindness is mostly seen in the Men. A statistics shows that in USA, 8% men and .7% women are color blind.

Answer 4

Color blindness in the human eye is caused from a number of different reasons. Some people may have been born that way, some may have contracted an illness. Glaucoma, Diabetes and Leukemia are some examples of becoming color blind.

Answer 5

Colorblindness would be a retinal deficiency. In particular, the cones of the retina do not detect the colors that typical cones can.

Answer 6

Color vision deficiencies can be classified as acquired or inherited.

Answer 7

Whether a person is colour blind or not, depends on genes inherited from either or both parents.

Answer 8

Inherit from parent or grand parent
