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.

  • Bernard Boxill's The Color-Blind Principle

    642 Words  | 2 Pages

    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.

  • Helen Nagel's The Miracle Worker

    654 Words  | 2 Pages

    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 Essay

    744 Words  | 2 Pages

    If one wanted to know their chance of carrying or having the disease creating a punnet square could help determine that. A normal person without Albinism or the presence of the allele melanin can be represented by capital “A” and another allele that represents the lack of melanin will be represented with lower case “a”. Since Albinism is an autonomic recessive disease, this means a person with a homozygous recessive gene will have the disease. Both parents must be heterozygous dominant and carry the allele; they will have a 25% chance of having a child with albinism and a 70% chance of having a child carrying the disease. If one parent is heterozygous that still carries the flawed gene and the other parent is homozygous dominant there will be a 50% chance their child will carry the disease but wont have a child with Albinism.

    Albinism is a genetic disorder that is caused by the lack of pigments. Sometimes it only affects the eye which is called ocular albinism. You can receive albinism from your genetics. You can be an albino in your eyes, skin or hair. It affects people of all races and all around the world. Studies show one in 20,000 people worldwide have some form of albinism. Certain forms of albinism are more common in some populations. Most common form of albinism is OCAZ and is found in one in 36, 0000 Caucasians in the United States. There are four types of albinism; type 1 is characterized by white hair, very pale skin, and light colored eyes. Type 2 is less severe their skin is usually a creamy white color and their hair could be a light yellow, blonde or light brown. Type 3 has a form of albinism called “rufous oculocutaneous albinism” this usually affects dark-skinned people. They have reddish-brown skin, ginger or red hair and hazel or brown eyes. Type 3 has milder vision problems. Type 4 has the same symptoms similar to type 2. Types 1 and 2 are the most common forms; types 3 and 4 are not as common.

    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”

  • An Anthropologist On Mars Summary

    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.

    The genetic defect that causes albinism in other types of albinism is unknown, but it is speculated that it involves other enzymes used to make pigment. Albinism is passed from parents to their children through genes. For nearly all types of albinism, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation, but still carry the gene. When both parents carry the gene, and neither parent has albinism, there is a one in four chance at each pregnancy that the baby will be born with albinism.

  • Severe Combined Immunodeficiency (SCID)

    626 Words  | 2 Pages

    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

    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.
