Color Blindness
Color blindness, also know as color vision defects, is the difficulty or inability to tell the difference between some shades of colors. Frustrations for those with color blindness include reading color-coded maps, buying clothing, and traffic lights.

What gene causes color blindness?
i don't know... is there a genetic connection???
Im wondering the same thing. Is there a genetic connection? I concluded that there is not an genetic connection, that dark hair has dark eyes for example. But i do however thing that there is a environmental connection. Both hair and eye color is effected but the environment (sunny, not sunny)
Who discovered that color blindness was a disease?
John Dalton "discovered" color blindness after he was looking at a Pelargonium zonale(a kind of flower). Dalton saw the flower as blue, whereas it is in actuality, pink. Dalton noted this fact in 1792
Are stick insects color blind?
No. They see like all other insects see. There are many colours in their eyes which only allows them to see blured colours.
Actually yes most of them are colour blind but some see blurred images.
Color blindness is a sex-linked genetic disorder. The reason that it is more prevalent in males is because the disorder is linked the the X-chromasome. If a male inherits an X chromosome that is defective, then they will be color blind. However, a female has two X chromosomes which means she can receive a defective chromosome and only be a carrier of the mutation. If she receives two defective x chromosomes, she will be colorblind.
Women can not be colorblind, only men. For questions like these a punnett square is useful. Men can not carry the colorblind trait, but women can. I know this is kind of confusing.
When a carrier ( a woman with the color blind trait) has children with a man ( color blind or not) her kids will have 50% chance of having that trait. If its a girl, she will be the carrier. If its a boy, he will have the colorblind trait.
SO TO ANSWER YOUR QUESTION:
Theoreticaly, 1 of the daughters will be the carrier, and the son will have a 50% chance of being colorblind.
Women can be colorblind, its just rare. About every 6400 women one is colour blind and with men, every 80 men 1 is colour blind.
A man with colour blindness will see red as?
A man with color blindness may have difficulty distinguishing red from green or confusing red with other colors depending on the type of color blindness he has.
What foods help in the prevention of color blindness?
There are no specific foods that can prevent color blindness. Color blindness is usually inherited and cannot be prevented through diet. It is caused by a genetic mutation that affects the photoreceptor cells in the eyes.
What are hemophilia and red-green color blindness?
Hemophilia is a genetic disorder that impairs the blood's ability to clot properly, leading to excessive bleeding. Red-green color blindness is a genetic condition that affects an individual's ability to distinguish between red and green colors. Both conditions are inherited and can vary in severity among individuals.
Turpentine is brownish yellowish kind of liquid that is secreted from some kinds of trees.
When all colors combine you get?
we will get black color when all the primary colors(RGB)* combine.
* R-red; G-green; B-blue
the combination of these primary colors in different proportions gives the different shades of colors. when all these colors combine we will get black.
Depends on what you are mixing. :-) If you are mixing colored light, then mixing all colors gets you white. If you are mixing paint, it depends on the proportions, but if all are equal, you get black.
A nucleolus is the ''core'' of the nucleus. It is large and round.
Are male children more likely to go bald later if their father has baldness?
Male pattern baldness is a genetic trait that comes from the mother not the father.....it makes no difference if the father is bald....but if you want to know if the son will be bald you can get a good idea if the mother has any brothers who are bald.
Which color moving object in a dog's peripheral vision will distract it the fastest?
Research suggests that dogs are most distracted by the color red in their peripheral vision, as it is the most noticeable to them. Red objects may capture a dog's attention quicker than objects of other colors.
How do you know you are the color blind ones and the people who are color blind aren't?
Color blindness is determined by genetics and results from a specific gene mutation. Those who are color blind lack certain types of color receptors in their eyes, leading to difficulty differentiating between certain colors. This condition can be diagnosed through a series of tests performed by eye care professionals.
What is the last color people see before they go blind?
The last color people typically see before going blind is black or dark gray. This is because as vision deteriorates, the ability to perceive color diminishes, and eventually, everything may appear dark or black.
Heliotrope is a purplish-violet color with hints of blue and red. It is a medium to dark shade of purple that can vary in intensity.
What is the normal color of a woman's scalp?
Depends what colour the woman is. Everyone is different, so would be the skin colour of everyones scalp. It would always be lighter then the rest of your body, if you've got hair. If your black, it would be black, if your white it would be white etc etc.
How do you test to identify a bad resistor?
First you need to know the value of the resistor. Follow the link for a handy resistor calculator
After determining the value of your resistor simply test the resistor with an ohmmeter to see if it is at true value. General use should be within + or - 5%
What kind of weather during the year causes the bright color of Autumn foliage?
More days of full sunshine during the months of August and September, along with with temperatures above 50 degrees F. days and below 40 degrees F. (but above freezing) nights, right before and during the three-week change period will result in the most brilliant color formation of leaves during autumn.
If 4% of males in a population have red-green color blindness, then the allelic frequency is 4% in males and in females. If mating is random, then in females, 92.16% do not carry the allele on either X chromosome, 7.68% carry the allele on one X chromosome, and 0.16% carry the allele on both X chromosomes. We have the dominant allele with frequency p and the recessive allele with frequency q, so 0.9216 + 0.0768 + 0.0016 = p^2 + 2pq + q^2 = (p + q)^2 = (0.96 + 0.04)^2
Where is the color green mostly found?
The color green is predominantly found in nature, such as in plants, trees, grass, and leaves. It is also commonly associated with growth, renewal, and tranquility. Additionally, green is a popular color in interior design and fashion.
What is the color of the salicylic acid-Fe3 complex?
When this salicylate dianion is mixed with an acidic solution of FeCl3(aq), iron(III) chloride, a highly colored (VIOLET) iron (III)-salicylate complex is produced. The maximum absorption of the complex is at about 535 nm.
To become a chemist, typically you will need to earn a bachelor's degree in chemistry or a related field. Some positions may require a higher degree such as a master's or PhD. Gaining research experience through internships or co-op programs can also be beneficial for career advancement in the field.
The bluish-black to bluish-purple color can be a sign of pregnancy. It is called Chadwick's Sign. It is caused by increased blood flow to the cervix/uterus. Inner vaginal lips can turn blue during pregnancy but this doesn't happen to every pregnant woman. Do a pregnancy test.
What percent of men and women display colorblindness and what is the cause?
The percentage of men who exhibit some sort of colorblindness is between 5% and 8%, and only about .4% of females. Usually, It is caused by a genetic mutiation in which the chromosomes are missing the genetic code for some of the cones in your optic nerve. Each cone has a different pigment sensitive to different kinds of light. In those that exhibit colorblindness the peak color wavelength is lower than someone with normal vision. The most common cause of colorblindness is from genetic inheritance, but it can also be caused by a disease involving the retina or the optic nerve, or due to damage to a part of the visual cortex in the brain. Some drugs have been known to cause colorblindness as well, such as hydroxychloroquine (Plaquenil), a drug used to treak patients with rheumatoid arthritis. Until now there is no cure for colorblindness.
