    Hemophilia is a genetic disorder, caused by a mutation, results in a person lacking a certain blood clotting factor. Essentially, hemophiliacs aren 't able to clot blood properly, which could lead to bleeding out and death. Normally, there is a 1 in 5000 chance for male births, while annually, 400 babies are born with hemophilia. It’s caused by a recessive gene that lies on the female X chromosome. Symptoms include excessive bleeding and bruising. This disorder is unique in that it’s commonly found in males. Females are most commonly carriers, but rarely have the disorder. This is due to the fact that it is a sex-linked recessive gene that’s on the x chromosome, which guys only have one of, while females have two. Phenylketonuria (PKU) PKU, short for Phenylketonuria, is genetic and metabolic disorder that results in body producing an excessive amount of an amino acid that’s detrimental to person’s brain. With a 1 in 15,000 birth rate, PKU results when a rare but recessive autosomal gene insufficiently produces an enzyme that is responsible for breaking down the amino acids phenylalanine. The buildup of phenylalanine in the body causes parts of the brain to be damaged. Symptoms can include seizures and retardation. To help treat this disorder, where the body produces an exorbitant amount of phenylalanine, the person must be placed on a strict diet that is void of high proteins.…

  • Allele Frequency Law Research Paper

    Hardy­Weinberg Law Given the mathematical and statistical methods used already, this law also uses probability, however is represented in a graphical manner. Through this graph I will determine if the class data set has significant variation on an allele by genotype graph by comparing their points to the collection of data sets from Census at School that will represent in this paper as the Canadian average. The Hardy­Weinberg Law, developed by G.H Hardy and Wilhelm Weinberg in 1908, states that…

  • Tay-Sachs Disease

    Tay-Sachs is an inherited disease that destroys neurons in the brain and spinal cord.

Infants will begin to have seizures and develop hearing and vision loss, intellectual disability, and paralysis as the conditions…

  • Essay On Random Breeding

    The results of the statistical comparison of genetic variability between the wild and founding population suggests that because the assumption figure is less than 0.5 (see table 2) the null hypothesis could not be dismissed. This meant that there is was no difference between the wild and founding population’s genetic variability. In relation to conservation biology, this finding is rather optimistic. Due to the fact that the two populations genetic variability is close to one-another allows for…

  • The Three Types Of Genetic Testing

    testing will find changes in the number of chromosomes and when there are large changes in the DNA structure. A disability that is identified by karyotype testing is Down syndrome. This is identified by and extra copy of the twenty-first chromosome (FAQ) The final test used for genetic testing is biochemical testing. This form of testing looks at activities or amounts of important proteins. If there is a change in the normal amount or activity of a protein this can be a sign that genes are not…

  • Genetic Predispositions

    cause the disorder. The results of this test will show if a couple that falls in the pool of candidates will have offspring with this genetic disease. Prenatal testing is performed on a fetus in-vitro to inspect its genome to see if it is predisposed to have a genetic disease or to detect mutations in its genome. This test can assist expectant parents in making informed decisions concerning their pregnancy or develop a plan of treatment for when the fetus is born. However, this test is not…

  • Flowers For Algernon: Science Or Science Fiction?

    or mutated superhumans derived from a science experiment gone wrong. Unlike the typical science fiction story, Daniel Keyes focuses on the impact that science and technology has had on the protagonist, rather than the world. Though this story does not focus on the impact of society, it still fulfills the purpose of science fiction. As Robert Sawyer once said, “[science fiction] is not to predict the future. Rather, it's to suggest all the possible futures—so that society can make informed…

(CDC, 2008) Autism Theory The MMR-autism theory came to the forefront when, in 1998, Wakefield and colleagues reviewed reports of children with bowel disease and regressive developmental disorders. The researchers suggested that MMR vaccination led to intestinal abnormalities, resulting in impaired intestinal function and developmental regression within 24 hours…
