Red Green Color Distortion
If a color blind person is red-green color blind, can they still see most shades of those colors normally?
Altered perception: They will see shades of color in all colored objects but will but see the full range, so colors that might appear bright to you will seem attenuated to the color deficient and some colors will seem what you might term brownish. The mixture seen depends upon the depth of the color blindness in each individual. Because of this most color deficient persons adopt rather bland wardrobes. ...Read moreSee 1 more doctor answer
Somewhat: The colors in color deficiencies lose their distinctive character (technically become desaturated) so that distinctions are blurred and many greens and reds in the most common form become poorly distinct. The actual color is not know as this is a psychological phenomenon and the color deficient identify many colors the same that a 'normal' would call distinct. ...Read more
Varies: In red-green color deficiency there is a shift in the perceived spectrum of colors and some reds and greens appear the same while others can be distinguished. A more common form which is a deficiency instead of absolute blindness causes a saturation shift in perception of colors but a full palette of colors is possible with mistakes made in some recognition. ...Read moreSee 1 more doctor answer
Nearsightedness is a recessive trait. red-green color blindness is a sex-linked recessive trait, what does this mean?
An Autosomal: Recessive disorder: Both parents are unaffected carriers of a mutant gene. Each of their children has a 25% chance of inheriting the mutant gene from both & having the disorder. X-linked recessive: Mom carries a defective gene on one of her X chromosomes. Each son has a 50% chance of inheriting the X chromosome with the mutant gene & having the disorder; each daughter, 50% of being a carrier. ...Read more
Can you advise for bio question- a mother has red-green color blindness. her husband is not affected.?
Inheritance: For a woman to have red-green color deficiency she has inherited an defective gene both of her parents. This means all of her children will carry the defective gene. If her husband is normal then only the mother can pass on the trait. So: all of their sons will be color deficient and all of their daughters will be a carrier with one normal (from DAD) and one abnormal (MOM). ...Read more
Red-green color blindness is caused by an x-linked recessive gene. In a family, the mother is a carrier of this gene while the father does not have the gene. What are the possible effects on their children?
I'm aware there's red-green colorblindness, but is there such a thing as not being able to see just red?
No: If you were color normal, and awoke with this deficiency, i would be very skeptical. This is simply not possible. You can find color deficiency charts on the internet - open one up and test yourself. I suspect you are ok. There is a rare stroke related color deficiency in older folks due to failure of the brain to register color but this is an old folks problem (described by oliver sacks). ...Read more
