Colorblindness Colorblindness affects more people than you might think, around 1 in every 12 males have color blindness (CBA). Although it is more common for boys to have color blindness girls can also get it, about 1 in 200 girls will have colorblindness (CBA). Look around you; chances are someone you know has colorblindness. There is nothing these people can do about it; it is a genetic disease. More men have this disease because of the way it is passed down by the chromosomes. The X chromosome is the cause of colorblindness. Since boys’ chromosomes are XY’s they only need one affected X to be affected. Since girls have two X’s and colorblindness is a recessive trait, they would need to have two affected X chromosomes, where the boy only needs one to be affected. As a girl you can be a carrier and pass colorblindness down, this means you have an both a recessive and dominant colorblindness chromosome (Xx). If you are affected both X’s are recessive (xx) and if you are colorblindness free you have two dominants X’s (XX). As a boy it is much easier to get colorblindness and that is why the ratio of boys who have it is much higher than the girls who are affected. Boys can either be affected of not affected; they cannot be carriers like girls. If a boy is colorblindness free he has a dominant X and normal Y (Xy). If he is affected he had a recessive X and normal Y (xy). The only way a boy can pass down the trait if he has it and his mate is a carrier or also has the disease. Although there is no way to treat colorblindness the people who have it have never known any different; it is not that big of a deal to them. I’m sure that people with colorblindness wonder what it’s like to see color the way other people see it, but t... ... middle of paper ... ...eyes were dissected (Colblindor). Even though we know what causes colorblindness, there are no cures for it. The only thing that could solve colorblindness is making sure this disease is not passed down anymore than it has already been passed down. I do not think that we need to go to such drastic measures as to stop people from having kids just to stop a hereditary disease from being passed down. This disease is not worth all that trouble and sacrifice, these people have never known any different and it is not that big of a deal. At first it may seem like a big deal realizing that they can not see colors the way we can, but that is jus because we have had the chance to see the colors the way they were meant to be seen. It would be really hard on someone to go colorblind after birth, but since this disease is started from birth, they do not know any different.
The Color-Blind Principle is written by Bernard Boxill discusses how color-blind and color-conscious are two very different things. This work also discusses the problems of discrimination based on something you are not responsible for such as being born black or white. Boxill uses the example of a university denying the rights of students’ admissions because their hair is parted to the right, then later states, “Suppose again for example, that a person is denied admission to law school because he parts his hair on the right side. Though he, far more easily than the black person can avoid being unfairly discriminated against, he does not thereby more easily avoid being the object, indeed, in a deeper sense, the victim, of unfair discrimination.” (463) I disagree with Boxill’s affirmative action idea because the idea of affirmative action is passing the discrimination from one race to the other.
When pondering on life as not only a blind child but also a deaf child, one might say perception of the world and life is impossible. In the movie The Miracle Worker, Helen Keller was blind, deaf and mute since she had been a baby. Helen was incapable of communicating to anyone. The question, “do you think she had an accurate idea of color,” to me, is defined through her inability to know the difference between colors and physical appearance on objects certain colors, for instance the sun being yellow. Because Helen was blind and deaf, she could not actually see the color pink or yellow I can see. Helen had never actually seen color; therefore an accurate idea of a color is nearly impossible.
Albinism is a genetically linked disease and is presented at birth; it is characterized as a lack of pigment called melanin that normally gives color to a person’s skin, hair and eyes. This results in milky white hair and skin, and blue- gray eyes. Melanin is synthesized from amino acid called tyrosine, which originates from the enzyme tyrosinase. Albinism affects all races and both sexes; people with this disease have inherited a recessive, nonfunctional tyrosinase allele from both parents (Saladin 189). The inheritance of Albinism is coded in the gene of the parent’s alleles. Alleles are two different versions of the same gene or trait and are found on the same place of a chromosome. One allele is coded for the production of melanin that will produce normal skin, hair and eye color and another allele that represent the lack of melanin that produces abnormal skin, hair and eyes.
You should have your child see a doctor when it’s born if the child lacks pigment in their hair or eyes. The doctor should follow them closely doing eye exams and blood work. Another way to tell if your child might have albinism is at birth the child has movement of their eyes back and forth or turns like a rotary (nystagmus).
An Anthropologist on Mars by Oliver Sacks introduces seven neurological cases that happens to people around the world. Sacks deals with different aspects of the brain, such as, the lobes of the brain, perception, and neurological disorders. One of the cases Sacks mentions is “The Case of the Colorblind Painter”. The case involves an artist who can’t see color due to an accident he encountered. His colorblindness affects his daily life, including his dreams; he doesn’t see a wide range of colors in his life, only what he describes it as “a black and white tv screen”. When I was reading his case, I found it intriguing that one can develop colorblindness from an accident. I always thought that colorblindness was a genetic thing, but the fact that at any given moment, it can activate shows that the brain has more mysterious than intended. The powerful emotional aspect of the case makes it more powerful and shows a deep theme. It makes me realize that I shouldn't take anything for granted because at any given moment, something can be taken away.
Achondroplasia is not usually inherited. When it is, achondroplasia is inherited in an autosomal dominant way. This is because the gene is located on a non-sex chromosome that is always shown when there is this genetic disorder in the DNA.
The “colorblind painter” loses his vision that was caused by a car accident. Due to the car accident the “colorblind” painter experienced carbon monoxide poisoning that also contributed to the car accident. “Mr. I’s life changed completely due to losing his vision from the car accident and know faces sudden life changes, such as him being colored blind” (Sacks, 1995, P.4,5,6). The “colorblind” painter experiences himself visiting ophthalmologists and neurologists to hypnosis and can’t distinguish different colors for some reason because of his loss of vision. “The “colorblind painter” deals with having a hard time seeing colors, such as red and green, or other colors that are different to distinguish colors responding to cones, of the retina”
Severe combined immunodeficiency (also known as SCID) is an uncommon genetic disorder. SCID drastically affects the immune system, harming the T and B cell functions (Severe combined immunodeficiency). More people tend to have X-linked SCID. Males only have one X chromosome and one Y chromosome. Mothers would pass their X chromosomes to their sons. In X-linked SCID, a mother with a defective X chromosome for SCID would pass this gene onto her son, since he only has one X chromosome (Severe combined immunodeficiency). Thus, males have a higher chance of getting X-linked SCID than females (females have two X chromosomes, so if only one of the X chromosomes has the defective copy of the SCID gene, then the female would probably be a carrier for
Their eyes are usually very light blue (may even appear to be clear), or in some rare cases to be brown. Their eye color can change with age. With lack of pigment in the eye, this means that irises will not be able to black the sunlight from coming into the eye. Since the iris does not have a lot of protection, this could cause the eyes to appear pink or red at times. Vision can be affected by this condition. It can cause server nearsightedness or farsightedness. This means it will be difficult to see things up close or far away. Blurred vision and have sensitive eyes towards the light. Another problem with vision is the movement of quickly moving your eyes back and forth. Albinism can cause a lazy eye also. People squint their eyes more often to sheild their eyes from the sun. Optometrist can help the senstivitie of the eye by subscribing contact or glasses to the
Colorism has became a huge issue in today’s society. Colorism is an issue because, it is a form of racism, it reflects back on the days of slavery, it is overall rude, and jail terms are affected.
My artifact of play is the video game “Call of Duty”, this is a first person shooter game that takes places during different wartime periods. I would like to focus on why Call of Duty games do not have a setting for color blind people. COD is a game that a lot of people enjoy but if you are color blind it might be hard for you to enjoy the game for example; some times in the campaign mode you might have to do a certain task that involves picking up something that has a certain color. If you are color blind it would be hard for you to complete the task and move on in the campaign to the next mission because you cannot complete the task. COD developers should use Battlefield 4 as an example because BF4 has a color blind setting for color blind
‘“Usually”’ is accurate, because sometimes a brown-eyed person is a carrier of the blue-eyed gene. In that case, in blue-eye/ brown-eye couple, every child will have at least one blue-eye gene (from the blue-eyed parent) and has a 50/50 chance of having another blue-eye gene (from the other parent).” (Berger, 2014, p. 56). “If two brown-eyed parents both carry the blue-eye gene, they have one chance in four of having a blue-eyed child.” (Berger, 2014, p. 56). In the case of dominant and recessive genes if the person has the dominant gene in any of the combinations listed above then that (dominant gene) is what is shown to the world. If you have a dominant recessive gene then the dominant gene is shown though you also carry the hidden recessive gene. “It is also possible for both parents to be carriers, in which case their children have one chance in four to inherit the recessive gene from both parents.” (Berger, 2014, p.
Color vision deficiency occurs when there is a problem with the pigments found in certain nerve cells of the eye called cones. Pigments are color-sensing granules found in cones. Cones themselves are found in the retina which lines the back of the eye and is light sensitive. There are several different forms of color vision deficiency caused by missing pigments inside the retina. The most common type of color blindness is a missing pigment that causes a person trouble seeing the difference between red and green. If a different pigment is missing, that person might have trouble seeing blue and yellow colors. It’s also possible to be missing more than one pigment causing trouble seeing or telling the difference between several different colors (Board).
People with ocular albinism, which only the eye lacks melanin pigment, while everything else appears normal. People who have this have a variety of the eye disorders because of the lack of pigment impairs normal eye development. These effected are extremely sensitive to bright light. Treatment for ocular albinism includes the use of visual aids and surgery for strabismus.
One can be born with a genetic fault that results in a colour deficiency, but it can also be acquired due to chronic illness, accidents or a stroke that damages parts of the brain responsible for vision. Genetic inherited colour blindness cannot be treated, but there is hope on the horizon for a cure. Acquired colour blindness can potentially be cured by treating the disease that results in a colour
