The purpose of this study is to aid families of patients and other research projects with colorblindness. The data for this study can be accumulated quite easily. Firstly, the genotypes and phenotypes of carriers and affected humans are to be compared to determine the pattern of inheritance. Doing so, it will come to your attention that colorblindness is a genetic condition where it is inherited from the mother. Also, another important result is that red green colorblindness is more common in men than women. In conclusion, colorblindness can be inherited through your genetics or even by certain diseases.
The purpose of this experiment was to lead a research study designed to obtain genotype and phenotype data from families affected by colorblindness.

The reason why I made the choice to study colorblindness is because colorblindness intrigued my interest the most, and I would like to learn more about this genetic condition. Not only that, colorblindness is a genetic condition where it is inherited from the mother. Therefore, my interest lies in obtaining valuable and factual data that supports this theory. Color blindness is not a form of blindness, rather is it an inadequate way in which one sees colors. Color blindness is most frequently inherited from mutations on the X chromosome. A defective X-chromosome triggers red-green color blindness-most common form of color blindness. Red-green color blindness is a sex linked recessive trait, and blue-yellow color blindness is an autosomal dominant trait. The faulty ‘gene’ for color blindness is only present on the X chromosome. Therefore, for a male to be colorblind, the colorblind ‘gene’ must appear on his X chromosome. Similarly, a female must possess the ‘gene’ on both her X chromosomes. According to Prevent Blindness America, approximately 8 percent of males and less than 1 percent of females have color vision troubles (Bailey, Gretchyn, 2015). If a woman has one …show more content…
Our data graphically portrays the observed phenotypes of the offspring of parents with various allele combinations, presented as frequencies. Accordingly, colorblindness is an X-linked trait. If the dad is affected his genotype is NY, and the mom could be heterozygous (AY) or homozygous dominant (AA) for the trait. However, if the trait is rare then the carrier is heterozygous and unaffected, and she is most likely homozygous dominate for the trait.
The inheritance patterns graphically portrayed above for red-green color blindness can just as well coordinate with other sex-linked genes such as male pattern baldness. Typically, since sexlinked genes are only conveyed through the X chromosome, colorblindness is recessive to the gene with normal sight. Since males only have one X-chromosome they only have one sex-linked gene, therefore they are hemizygous. Meaning they only have a single copy of a gene rather than the ordinary two copies (Hemizygous, 2012). In terms of females, since they have two sex-linked genes, they are either homozygous or heterozygous. Homozygous labels a genotype with two identical alleles at a certain locus, while heterozygous labels a genotype containing a single print of a gene in a diploid organism. From the following genotypes: Genotype of affected male (AY), genotype of affected female (AA), genotype of non-affected female (NN), genotype of non-affected
Colorblindness is a defect in the perception of colors, caused by a deficiency in specialized cells in the retina that are sensitive to different colors. The term is often used today during political discourse, often by members of some factions of liberalism, when claiming that one’s race should be irrelevant to any decision making process. It is a form of moral posturing; that one should see an individual as simply an individual, but not as part of any larger group or culture. As if this philosophy will enable us to bridge any gaps between races, this thought attempts to focus on how we are all the same, rather than how we differ.

colorblind practices can be inequitable. I then draw on normative principles from social theory to defend
Color blindness refers to a society where there are no special rights, privileges, or importance attached to person’s race. This concept confirms the values of fair play and equal opportunity. Some appealing elements to this ideology are the reversal or removal of drama from social, economic, and political incorporations of minorities. For examples, no more racial slavery, exclusions, genocides, or invasions of cultural groups in the United States.
Colour blindness can is often carries the mutated gene on the X chromosomes that it passed 50% of this over to the child, the mother may not have had colour blindness but it would most likely be carried on one of the X chromosomes, If the mother is the carrier and the father doesn’t have colour blindness there is a one in two chance that the son may have the disease while for the daughter there is a one in two chance that she would be the carrier of the disease and there being no chance in her getting it. (National Eye Institution, Accessed 22.08.2015). If both of the Parents are carriers that means that there is a one in four chance that the child would most likely have the disease, one in two that the child is a carrier of the disease or a one in four chance that the child isn’t a carrier of the disease and also doesn’t have the disease although it is most likely that one of the children would end up getting colour blindness if one of the parents happen to have it (National Eye Institution, Accessed
When I hear the term colorblind it makes me think we are supposed to ignore part of the human. It's like they're trying to tell us that race no longer “matters” in American society. I personally hate this term, if you ignore something and act as if a problem doesn't exist. It just gets bigger and bigger and doesn't go away. Then negative feeling or the issues become worse or more intense, especially through long-term neglect or indifference. It's just like anything in life if you ignore something by the time you go back to it, the problems harder to clean up.
The idea of a colorblind society assumes colorblindness is a something we should hope to achieve. But does colorblindness help or fight racism? Colorblindness treats racial inequality as prejudice on an individual basis. This enables it to ignore what has happened in history. By being colorblind, we are fixated on a past understanding of race and racism. Embracing color blindness eliminates racial awareness and thus eliminates the need for accountability for the white supremacy that exists in America
Colorblindness can refer to the fact that to a certain extend colleges/universities are still segregated, for example, “It is not my fault that I am able to afford college, while minorities cannot because they can’t find decent jobs.” This idea that it is ‘not their fault’ contributes to segregation because the people decided they have no part in that specific aspect of society. Although, colleges/universities are trying to desegregate their campuses and promote diversity; there are still aspects of segregation on campuses and it might not be specifically called segregation, but it is through the students social behaviors and tendencies. Therefore, to view this idea, research will be done on a specific college campus, Saint Mary’s, focusing on the different races/ethnicities of the
Because one can be a wizard with only one gene expression, the trait could be sex-linked, passed down through the X and Y chromosomes that determine our gender. In modern science, it wasa determined that sex lined genes passed through the X chromosome were not recessive nor dominant; just sex linked. (Dobyns 11). Because there were previous studies on sex linked traits, like how two parents with color blindnesss (recessive) have a daughter or son, they could also inherit color blindess (CITE). Because of new studies showing that the x linked traits to not follow the same rules as normal inheritance, the original theory presented in this paper holds true. The number of female and male wizards is proportional, but if the trait was sex linked, then every family with any wizarding genes would have all boys born become wizards, while only females who were born to two wizard parents could have magic. Because this is not true in the book, as seen with the number of half blood and muggle born female witches, readers can know that the trait is not sex
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
Red-green colorblindness is usually inherited in an X-linked recessive way and it affects an approximated 6 percent of men in the world. This means that, the disorder is usually passed to the affected persons through the X chromosomes thus making the condition to be experienced more by men than
Based upon observation of the F1 generation, we hypothesize that the inheritance of the white-eye (W) mutation is sex-linked and recessive wild type.
This paper considers that focused primarily on human iris. This choice of this topic was made due to interest of wanting to provide knowledge about the factors that determine eye color. I know, like hair or skin, brown eyes are dominant over blue eye genes. I also know that a person can be identified by the retina scanners because everyone has their iris with unique structural patterns.
The gene carrying the defect that produces albinism is recessive, which means that both parents must carry this recessive gene in order to produce a child with the condition. When both parents carry the gene (and neither has albinism), there is a one in four chance with each pregnancy that their child will have albinism. The inheritance pattern of ocular albinism is alittle different. This condition is X-linked, meaning that the recessive gene for ocular albinism is located on the X chromosome. X-linked ocular albinism appears just about only in males who inherit the condition from their mothers.
This table helps show all the possible genotypes from one set of parents. The table shows that the genotypes purple and starchy are dominant, and the genotypes yellow and sweet are recessive.(stallsmith)
Color blindness is most common in males and it is known that 1 in 12 men suffer from the condition, although there is speculation that a significant percentage of the male population may have some sort of color vision deficiency without even realizing it. An estimated 1 in every 200 women are affected by color blindness, which makes for a total of 300 million color blind people across the world.
