Color Blindness: Genetic Disorders

colorblind practices can be inequitable. I then draw on normative principles from social theory to defend

How eyes see color is pretty simple, our retinas approximately six million cone cells. Each cell in the retina is assigned to a certain color. There are three different types of cone cells, blue, green, and red, which correspond to the three primary colors. Being colorblind is more likely to happen to boys than to girls. By reading the article after the colorblind test I also learned that people who suffer from being color blind are not blind to a color, but have trouble seeing a certain shade of a color. Another, thing that I learned is that being colorblind can be inherited genetically or if you damage one of genes “photopigments” you also can become color blind. If I had never read this article, I would have never learned all this interesting and great knowledge to

The way color-blindness is supposed to work, it's believed since the Civil Rights Movement white peoples attitudes have demonstrably changed, racism is no longer embedded in the U.S or

Color blindness is generally defined as the inability to differentiate between certain colors. In regards to society, refers to intentionally ignoring racial color when determining

In another research conducted by Dr. Gerald Jacobs, Professor of Psychology at the University of Santa Barbara, dogs were given three circles of varied colors and were taught to choose the one that looked “different”. The dogs couldn’t pick out the odd one out when they were presented with colors they supposedly couldn’t detect. However, when they were offered with colors that they can perceive, they were able to point out the “different” one. Through this test, the researchers were able to conclude which colors dogs have trouble detecting, and which ones they can see with no problem. This also cemented the idea that dogs see in dichromatic vision, same as color-blind

Organisms possess several types of color vision depending on what wavelengths they are sensitive to. Humans are trichromatic, because their vision is formed by long, middle and short wavelength sensitive cones (Carroll, et.al, 2009). Depending on the environment, primates will have different variations of color vision. (Melin, et.al, 2017). Routine trichromacy and polymorphic trichromacy both track different food sources. Routine trichromacy is helpful for tracking down reddish-yellow fruit and seasonal leaves while polymorphic trichromacy is helpful for tracking down ripe fruits and insects (Melin, et.al, 2017).

Being able to see color is one of the things that make humans special but sometimes color can deceive us. Humans perceive color based upon the lighting and other colors around whatever the object they are looking at is. For example an apple can be seen as bright red if the colors around it are lighter or the light is hitting it straight on but the same apple can be seen as dark red if the colors behind it are darker or the light source is not focused on it

The article “Gene therapy for red- green colour blindness in adult primates” by Katherine Mancuso and her colleges is about the possibility of curing color blindness. This test was done on adult squirrel monkeys that were missing the L- opsin gene. Out of the three cones humans have (short (S), long (L), or the middle (M) photoreceptor) only the L-or-M cone is responsible for red- green colour blindness. Many female squirrel monkeys have the ability to access all three photoreceptors giving them the ability for trichromatic color vision, but males are dichromats meaning they are missing the L-or- M gene causing them to be color blind. In order to correct this color deficiency a third type of pigment was added to the monkeys retinas to provide them with the receptors that are necessary in order obtain trichromatic color vision. Over the span of a year the scientists observed that before the treatment the monkeys couldn’t decipher between blue green and red violet. After they started to develop a new pigment (due to the injection) in the cone photoreceptors scientists discovered that the monkeys now reacted to the colors they couldn’t see before. The scientists concluded primates benefited from the injection and that they were able to see colors they were invisible to them before, and that the findings in this experiment could

As many people have different appearance, people also are color blind. In recent day, people who are color blind usually treat from others, since they had contrary inner appearance. People who are color blind, they catch out the grass as orange. Either, they cannot distinguish between two different colors. To someone who are color-blind, a green leaf might look gray, and stunned observers eyed strangely. However, we could not detected anything erroneous with the “Eye”. People is completely matter of fact, usually, the overall situation is beneficial, despite a few minor problems. Nonetheless, there was already immense problem settle down on the middle of human’s perspective. Therefore, the people who were already color-blinded, receiving exceptional

Being colorblind seems like a great concept because people would be treated evenly because there would be no favoritism caused by ethnocentrism or racism. The problems caused by seeing people by color are too frequent now and plays a big role in what is now called modern racism. Usually people part of the dominant group, have no problems with modern racism such as problems like getting jobs and the discrimination that comes with it. I feel as though if everyone was colorblind everyone could have a fair chance. Not only would it give those that have less chances because of modern racism. It could also get everyone together and people would not judge each other as much as they do now. It could help unify everyone of different races, gender, ethnicities,

“Achromatopsia affects roughly 1 in 33,000 Americans.” (2) Achromatopsia is a condition in which a person loses partial or all of their ability to see color and can also be referred to as achromatism, rod monochromatism, or total color blindness. It is the result of a change in one of the following genes: CNGA3, CNGB3, GNAT2, PDE6C, or PDE6H. Achromatopsia is a disorder that affects the retina, which is the part of the eye that is sensitive to light and forms visual images. Inside the retina is two different types of light receptor cells, called rods and cones. These cells use a process called phototransduction to send visual signals from the eye to the brain. Mutations in any of the genes above disrupt the phototransduction process, affecting

If you are born with it, you will have to live with it. However, there is medical research going on to try to cure color blindness. They are using gene therapy on monkeys to get them to see color. Researchers hope that one day this will help humans too. Gene therapy helps repair the damaged chromosome that causes color blindness. If color blindness is caused by something else; like an injury to the eye, old age, glaucoma, or certain medication side effects, you must treat the underlying cause to fix the non-genetic colorblindness.

Colorblindness is the inability to distinguish the differences between certain colors. In order for a girl to have the genes for colorblindness the father must be colorblind. Women mostly carry the trait instead of fully expressing colorblindness. Since colorblindness is a recessive trait the mother must carry the trait and the father must be affected. In the image at the bottom of the page you can see that in generation four person seven is an affected female. Above that in generation three her parents are a carrier female and an affected male therefore, she gets the affects of colorblindness.

Introduction: The gene that codes for red-green color blindness, the most common form of color blindness in humans, is found on the X chromosome. One in 12 males is color blind. In females, however, color blindness affects only about 1 in 200. Why is

In conclusion there will always be advantages and disadvantages to being colorblind. Colorblindness has been around for a long time and we may never find a permanent cure. But being colorblind doesn't make you miss out on everything. You actually get to see things that other people
