Most do: Color vision is important & defects vary in their intensity a effect on various individuals. I wouldn't classify it as a significant reason to avoid having kids. If dad did i wouldn't be here. It didn't hamper in his professional career or me in mine. ...Read more

Why not: Color deficiency, usually in males, is because of a defect on the sex chromosome (the x) which is unchecked by the y (male) chromosome. If you have this, none of your children will be color deficient because your male children get a y from you and your deficient x goes to your daughter whose mother is undoubtedly color normal. Color deficiency is not a particularly big handicap anyway. ...Read more

X-linked: The most common colorblindedness is an x-linked trait. That means it occurs almost exclusively in males and is passed to them from a defect x from their mothers. Your mother could have gotten this gene from her mother. In this case, there would be no relatives with it. Ps. Ask your mother's father if he is color-blind. ...Read more

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 more

Ask your dad: Most people with color-blindedness function completely normally with regard to visual activiies. They just have some difficulty telling some colors apart. For example, greens and browns tend to look the same to them. ...Read more

Help please! is color blindness a gene disorder or a chromosomal disorder?

The same: Genes are the elements of the chromosomes and so a disorder of a gene will be carried on a chromosome (usually the x for most color blindness). It is like saying is an apartment the same as an apartment building. ...Read more

Hemochromatosis color blindness DNA testing influence, can you tell me?

What are you asking?: Can you clarify? Genetic testing for DNA isn't subject to much in the way of outside influences. Genetic work on colorblindness is available but we're not sure what to do with the data. The former is life-and-death. The latter is perhaps a target for gene therapy that will give fullcolor vision to those who haven't enjoyed it. ...Read more

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

What causes color blindness?

What causes color blindness?

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 more
