In Lab 8, we had analyzed remains found at a wooded area near Jonesburg and tried to determine if the bones belonged to a 28-year-old woman who had been reported missing from a city within the vicinity. Upon analysis, it was determined that they did belong to a female. However, it was not possible to determine if the bones did belong to the missing women. Lab 12 presented the opportunity to genetically analyze the remains found. DNA profiling, also referred to as typing and fingerprinting, uses genetic material to show relatedness and uncover the identity of organisms. Most commonly associated with forensics, it can be used in an array of scientific fields such as anthropology. One method that can be used, when a large sample present, is restriction…

The Human Genome project, a revolutionary study that spanned over 13 years, hoped to discover more about the DNA of humans. The study's main goal was to provide new information to help with the diagnosis, treatment and prevention of genetic disorders. From the substantial amount of information and knowledge acquired from the project, new ways to test for genetic disorders, and the probabilities of inheriting disorders was gained. Gene testing, which involved taking a sample of a persons DNA, helped screen for a number of different disorders and problems. Before genetic testing, couples at risk of conceiving a child with a particular genetic disorder would have to initiate the pregnancy and then undergo the testing, faced with the dilemma of terminating the birth if the results weren't good. But because of the new technology available, with the combined effort of IVF, sperm and egg cells can be removed from both individuals, and the eggs would then be fertilized within a laboratory. The embryo's would then be tested for genetic mutations,…
Concerning genetic testing in general, a study found that among those who were confirmed to have the Tay-Sachs recessive gene, “about half of the carriers expressed a sense of shocked surprise… having been found to have some imperfection” (Childs). A lack of understanding or a false misconception about the idea of “carrier” status results in discomfort and an unwillingness to be tested; preferring a state of blissful ignorance. Since Tay-Sachs is an autosomal recessive disorder, being a carrier does not mean one has an “imperfection” or one has the potential to develop the disease but that they have the potential to pass on the disease to their children. They also do not express symptoms of the disease-- a common misbelief. And, even despite being a carrier, it does not mean that one’s child would ultimately be a Tay-Sachs child or even a carrier; “if only one parent is a carrier, there is no chance the child will have Tay-Sachs...a 2 in 4 (50%) chance that the child will be a carrier” (“Tay-Sachs Disease”). A diagnosis is not a condemning statement, but makes the prospective parents aware of the “potential” harm that might befall the child, if both happen to be carriers. In addition, Rosner states that “if the purpose of Tay-Sachs screening is to provide eligible clients with genetic counseling about reproductive and mating options, few would argue against screening” (Rosner).The common stigma that genetic screening may be used outside of medical usage breeds the misconception that genetic testing is wholistically bad and may be used to harm the individual. However, Rosner argues, that genetic screening is inherently not bad, but the way we use it. However, on the topic of the latter method, prenatal screening is riddled with controversy, specifically with the ability to pick the reproductive route. Since…
Imagine a society in which your social status is based upon your DNA. A world where everyone knew everything about you. This description matches the plot of the aerospace thriller “Gattaca”. In the movie, genetic testing is common practice; DNA prejudice becomes widespread. Although this sounds far-fetched, this sort of DNA testing has been rapidly developing over the past decade. Personal Genomics is concerned with the mapping of an individual’s genes. When the Human Genome Project was completed in the early 2000’s, personal genetic testing was extremely expensive. Now that this technology has become more developed, the price has dropped. 23andMe is a direct to consumer genetic testing company that provides customers with personal single…
This final paper will discuss the ongoing debate of genetic/prenatal testing. Procedures for genetic/prenatal testing have been available since the early 1970's (Press, 2008, pp. 73-78). Genetic testing identifies abnormalities or changes in the chromosomes and genes. This type of testing is used to confirm or deny a suspected genetic condition or used to predict a person's chances of developing or passing on a certain disorder (Grant, 2000). Once the woman wants to go ahead with the genetic testing, a primary care doctor or genetic specialist places an order for the test. Genetic testing is often done as part of a genetic consultation (Press, 2008, pp. 73-78). It is very important that the patient knows every aspect of the procedure including…
Since the test involves taking only a small blood sample, where a person’s DNA can be found, these tests have a minimal health risk. Genetic testing was initially used in pregnancies to test for diseases like Down's Syndrome and other genetic disorders (“What are the...”). However, thanks to more recent improvements, genetic testing has come to display several weaknesses and strengths. The genes that can be obtained from infants can notify parents of possible physical deficiencies, while others may show physical advantages (Stein).…
Genetic testing has potential benefits, such as you can see if your chromosomes are positive for a genetic mutation. Test results can provide a sense of relief from uncertainty about having a mentally or physical ill child because no one wants that for your child. They also help people make informed decisions about managing their health care. For example, a negative result for the mutation can eliminate the need for unnecessary checkups and screening tests in some cases. A positive result, having the mutation, can direct a person toward available prevention, monitoring, and treatment options. Some test results can also help people make decisions about having children. Newborn screening can identify genetic disorders early in life so treatment can be started as early as possible.…
From a patient’s perspective, people tend to see genetic information as more definitive, in the sense that 'you cannot change your genes' and that 'genes tell all about your future.’ Such genetic determinism is an oversimplification and does not take into account the nature of biologic pathways. From a provider’s perspective, genomics presents challenges with respect to ethical and professional responsibilities, including the appropriate use of genomic information in the health care setting. I believe that there should be an identification of provider education programs that increase use of appropriate screening, counseling and evidence-based genetic tests. By increasing the effectiveness of genomic testing, it will help dissolve the negative association and further increase the proportion of people who are willing to receive genetic…
Genetic testing, aka DNA testing, allows doctors to check if there are any possibilities to inherit diseases, and can also be used to determine a person's ancestry or biological relationship between people. It is important to understand the background and implications behind genetic testing as testing may be able to identify the odds of have of having a child with a genetic disease, but it can also result in miscarriage. The test often cannot determine if the child will show symptoms of a disease, how severe the symptoms will be, or whether the disease will progress over time. Another thing to take into consideration is the absence of treatment strategies…
When completing the assessments and interpreting the results, I realized that there were various accurate elements I always saw in my family, and now they were proved over a simple questionnaire. However, some other elements, I found a little bit confusing, and I am still not so sure whether they are that accurate.…
Though there are tests and testing facilities that do the genetic tests, prenatal genetic testing is not accessible to all at-risk or concerned families expecting a baby. Government funding should be put towards prenatal genetic testing to increase accessibility to testing facilities, discover more testing forms, and give more autonomy to physicians. With these improvements, low income-families and anyone with a family history of genetic diseases can find out and prepare for any irregularities before the baby is…
