Genetic Cause Of Color Blindness
I have to do a genetic disorder report for class and was debating between color blindness and hemophilia. What are your opinions?
Both interesting: These are both fascinating diseases and the subject of much inquiry. Look on wikipedia and you will find much to talk about. The issues are quite different but the underpinning for each is genetic. The hemophilia has had impacts on history such as the family of queen victoria. Color deficiency has caused some famous accidents. Have fun. ...Read more
From a medical standpoint, "genetic" refers to the potential heritability of various medical conditions. While some conditions are inevitable (at some point in one's life) as a consequence of simple genetic heritability (eg huntington's disease), a large number of medical conditions (including all behaviorial health disorders) are the expressed final pathway of a ...Read more
Why am i color blind? What is the cause of color blindness? No one in my family has the gene that causes color blindness.
Blame your Mom: If you have red-green color deficiency, then you carry a defective x-chromosome which you got from your mom (i assume you are a male). Your mom was a carrier so she was color normal and you had a 50% chance of getting the abnormal x from her. So in fact someone in your family, mom, had the gene. ...Read moreSee 1 more doctor answer
Several: Color deficiency can occur with advanced diseases of the retina such as diabetes retinopathy and retinitis pigmentosa. Color vision changes can occur because of changes in the lens which alter color sensitivity. A few rare strokes in the brain can wipe out the color sensitivity. Most color deficiency is due to genetic changes in the chromosomes and is inherited. ...Read moreSee 1 more doctor answer
No: This is definitely not recommended. It is uncomfortable and most would not due it. It sometimes is done for religious purposes and by people under "the influence". The eyes focuses the sunlight and damages a portion of the retina where it is focused in a non-specific way so all receptors are damaged and color blindness does not result, just a loss of a portion of the visual field. ...Read more
Mostly genertic: In inherited color deficiency, a visual pigment has its spectrum of color reception altered to a small degree and to a large degree in those with high degree of this disorder. The photoreceptor count is the same, so the acuity is not lost - just the color recognition. There are a few less common color vision losses due to advanced retinal, optic nerve and CNS diseases. ...Read moreSee 2 more doctor answers
None: Colorblindedness is inherited. It cannot be caused by an accident. ...Read more
Too much sun?: The eyes have visual pigment that responds to color. Some are born with defective pigment and can not detect red or green. More common the pigment is bleached out due to too much exposure to light - especially sunlight. If you have been exercising too much in the bright sun you may become dehydrated and also find it difficult to see colors. Cooling off, liquids, rest, and dim light are needed. ...Read more
