The use of genetics and reproduction sciences has been an ongoing debate for years. Some argue that the use of genetics and reproduction sciences are unjust, unethical and inhumane. The other side of the debate argues that the use of such sciences is a “life saver”, that it will improve medical advancements, health, and society. Genetics and reproduction sciences are used for informing individuals about possible outcomes, abnormalities, and genes of current and future pregnancies. Genetic testing analyzes chromosomes, DNA, proteins, and genes to determine the presences of altering genes that cause disease or disorders. The sole purpose for using genetic testing is that is can confirm or rule out suspected genetic conditions. The test will help determine the probability of chance of developing or passing on the disorder.
Genetic testing can be processed in several ways: molecular, chromosomal, and biochemical testing. Molecular genetic testing refers to the study of genes, short strains of DNA used to identify variations or mutations that can lead to a genetic disorder. Chromosomal genetic testing analyzes whole chromosomes, long strains of DNA to identify the presences of large genetic genes and extra chromosomes. Biochemical genetic testing, studies the amount or activity levels of proteins. The presence of abnormalities found in the amount or level can indicate changes to the DNA that can result in a genetic disorder.
There are currently over 1,000 genetic tests
The Human Genome Project is the largest scientific endeavor undertaken since the Manhattan Project, and, as with the Manhattan Project, the completion of the Human Genome Project has brought to surface many moral and ethical issues concerning the use of the knowledge gained from the project. Although genetic tests for certain diseases have been available for 15 years (Ridley, 1999), the completion of the Human Genome Project will certainly lead to an exponential increase in the number of genetic tests available. Therefore, before genetic testing becomes a routine part of a visit to a doctor's office, the two main questions at the heart of the controversy surrounding genetic testing must be
One of the benefits of prenatal screening is to enable early detection of the developmental defect embryology. This embryology developmental defect may be due to the mutation or genetic inheritance. Mutation is a condition characterized by permanent change in the DNA sequence that makes up a gene. It can range in different sizes from a single DNA building block (DNA base) to a large segment of a chromosome. On the other hand, genetic inheritance is a condition whereby parents pass traits such as height and other characteristics to the children by chromosomes. “Sonograms, genetic tests and a new test called pre-implantation genetic diagnosis -- which is a genetic test conducted on embryos for people attempting pregnancy through in vitro fertilization -- allow women to better predict if the infant will have a genetic defect” (New York Times Magazine, 2006). Thus thorough these tests, medical practitioners are able to identify and make early preparation toward any abnormalities of the fetus.
The medical advances being made feasible by genetic testing are very exciting. It is possible for people with predispositions for genetic defects to know in advance if they will have a healthy child or not. If they find out there is a problem they can choose to terminate the pregnancy or they can prepare in advance for their child's special needs. There is even new technology called Ex Utero genetic testing. This test is performed on eggs fertilized through in vitro fertilization before they are even put in the mother's uterus. Understanding genes in the developing human will help doctors understand the nature of genetic diseases and may lead to countless other medical breakthroughs. Though it is probably a long way off doctors may one day be able to manipulate genes. If this is possible some genetic problems may be cured.
As you can see genetic testing is very important and can affect a child's and parents lives for the better and the worst. Children all over the world have serious genetic diseases that affect their life on a daily. Some of these diseases are Achondroplasia, Down syndrome, and Turner's syndrome. Many believe genetic testing is a good way to test for these genetic conditions before the child is even born, but others think that it can harm the baby very badly and even cause a miscarriage, so they choose not to do this kind of testing. Knowing about the most serious genetic diseases is very important for expecting parents to be informed as well as being
Gina Kolata’s article, Ethics Questions Arise as Genetic Testing of Embryos Increases (2014), explains that as the increase of the testing of embryos for parents to choose whether or not to have children has also brought its ethical questions in the light. Kolata uses the Kalinskys case, a family in the article, and how their neurological disease, Gerstmann-Straussler-Schinker (GSS), has raised questions for ethicists who have looked into the case. Kolata’s purpose in writing this article is to inform the audience on the growing topic of embryo testing and also the ethical question that also accompany in order to have the audience to develop a personal view on the issue. Given how the author explains the technical terms used within the article, Kolata is writing to an audience that is not fully aware of genetic testing.

Genetic testing is when tests are done on the blood and other tissue to find genetic disorders in an individual. It is used as a healthcare tool to detect gene variants associated to a certain disease or disorder, and is used non-clinically for paternity testing and forensics. There are many different methods of testing, usually done with a blood sample. Other methods include diagnostic testing, carrier testing, prenatal testing, pre-implantation genetic testing, newborn screening, pharmacogentic testing, and a few others.
Genetic testing identifies changes in ones genes and chromosomes. These changes often lead to diagnoses of conditions, disorders, or diseases. Through testing, “one can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or
Genetic testing, can affect a person’s life in many ways. Genetic testing is a type of medical testing that identifies changes that occur in chromosomes, proteins, and genes. These changes that occur can be associated, and often are associated with inherited
Genetic testing is a medical test of one’s DNA that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition which can help determine an individual's chance of developing or passing on a genetic disorder. In addition, knowing one’s genetic code can help individuals improve their wellness, prevent the onset of diseases they are at risk for, or lessen the harmfulness of diseases they do contract. NOVA’s documentary on PBS, “Cracking Your Genetic Code” demonstrates what exactly genetic testing is, how genetic testing is performed, and in addition the film showed stories about some individuals that have benefited from these special DNA techniques. The film plot focuses
Genetic testing has become a highly controversial issue among both the general population and the scientific community. It is a process that exposes a person’s entire genome sequence, allowing it to be read and evaluated to identify potential risks for genetic diseases or diseases that could be passed onto offspring (Holt Productions, 2012). With thousands of genetic tests already being used, and more being established, it seems logical to put this growing technology to use. Some agree that it is a person’s right to know and understand his or her genetic makeup. However, others argue that, despite the benefits of genetic testing, caution should be used to carefully inspect the risks associated with this new technology.
Everyone stands to benefit from the developments made in the field of genetics as everyone is made of genes. Genetics is the study genes and how they influence human biology. Genes are the molecular unit of inheritance found in cells, these genes encode everything about human physiology ranging from eye/hair colour to height, possible mental/physical disorders and so on. The field of genetic testing is concerned with advancements in the study of the functions of individual genes and how they influence living things. Major advances have been made in the study of the genetic structure of humans and external influences to our internal makeup, such as our quality of life and their implications that may have on our physical and mental development.
The distress and the health risk to the mother are concerns when viewed through the lens of the principle of nonmaleficence or of “do no harm”. The accessibility and cost of the prenatal genetic testing are contentious. Although prenatal genetic testing is considered to be a useful tool, some believe it leads us down a “slippery slope”. Controversy exists surrounding prenatal genetic testing for reasons of social, psychological, moral, and religious rationales.
In this critique, I will be discussing my opinion on Mr. Pollard’s article about genetic screening. These genetic screening began in the 1960’s and since then they have found themselves in the middle of major controversy throughout the years (Press, 2008). Genetic screening a series of test performed when a mother is pregnant in order to figure out whether or not her child may have a developing disorder. Some genetic screening are also performed after the baby is born. Genetic screening can play a major role in personal parenting decisions and medical treatment if and when deemed necessary. Although genetic screening has much debate surrounding it, testing for any potential disorders and diseases can be live saving.
genetic testing, everything has changed. She notes that clinicians now have the ability to diagnose, treat, and monitor a patient’s illnesses or disease progression in an entirely different manner. This is a far cry from the old medical model of responding to a disease (or defect) only after it appears, and then prescribing the recommended medication or intervention. These genetic medical advances sound miraculous and promising, but the ability to test, screen and provide early intervention does not come without many major ethical dilemmas.
