INTRODUCTION
Genetic diseases are abnormalities in an individual’s genomes where genomes are the complete set of genetic instructions which are essential for the creation of an organism. A disease is a structural or functional disorder which results in symptoms and a genetic disease would be the structural or functional

The disease has a recessive mutation with the haemoglobin gene causing an abnormal haemoglobin protein. This abnormality causes the haemoglobin to lose is original round shape and collapse into a sickle shape. Haemoglobin is an iron-containing protein on red blood cells (erythrocytes) that carries oxygen. With the change in the shape of the erythrocytes, the oxygen amount which is transported around the body does not reach its maximum potential because the maximum surface area of the erythrocytes is not reached. The disease occurs when there’s a recessive-recessive homozygous gene (e.g. bb) inherited from the parents and when there’s a recessive-dominant heterozygous gene (e.g. Bb) inherited from the …show more content…
The Human Genome Project (HGP) has resulted in an understanding of the human genes and therefore has brought about biomedical processes to eliminate unwanted genes.
• The Human Genome Project used several individuals who volunteered to map out the genome of Homo sapiens. A genome is a complete set of an organism’s DNA and with the knowledge of the human genome; errors can be identified and resolved if practically possible. The project offers hope for more and better methods of eliminating diseases plus finding error and preventing the errors.
Gene testing has become available and this allows for individuals to know whether they have the recessive genes of a genetic disease or not. After gene testing, the individuals are told whether they are allowed to have children or not, this then keeps the genes from being passed on. Gene testing eliminates any future encounters of the genetic disease with gene testing and preventing genetic diseases from being passed

Designer Babies: A Genetic Analysis
1393 Words | 6 Pages• The technology of designer babies is bliss for the couples who are unable to have children because they do not their genetic disease which they have. Through the process of pre implantation genetic diagnosis the embryos are scanned for genetic diseases and if found that it has inherited genetic disease the genetic makeup of the baby is changed so that the child could be born disease free. PGD can screen for about a dozen of the most serious genetic diseases including: cystic fibrosis, Tay Sachs, various familial cancers, early onset Alzheimer’s, sickle cell disease, haemophilia, neurofibromatosis, muscular dystrophy, and Franconia’s anaemia. With further testing of the human genome it is said that nearly all of the genetic diseases could
Movie Analysis: Designer Babies
1614 Words | 7 PagesAccording to Hemmy Cho’s article, Enhancing Humans Through Science Is Beneficial, “advances in genetics mean we don't have to rely on evolution. We can choose the genes that we wish to pass on to our immediate future generations and bypass the genetic theory” (Cho, Hemmy). Similarly, Jeremy Rifkin argues that “it would be cruel not to use new technology to eliminate serious disorders” (Rifkin, Jeremy). For example, “the most common, fatal genetic disease in the United States,” according to the National Human Genome Research Institute, is Cystic Fibrosis. This single gene mutation causes the body to create thick mucus which clogs the lungs and interfere with digestive enzymes from decomposing food.
Pros And Cons Of Curing The Future: Designer Babies
909 Words | 4 PagesCuring the Future: Designer Babies Diseases and outbreaks have been becoming more and more common in the world lately. Scientists have thought of a way to reduce these outbreaks and even diseases in general: designer babies. Pre-implantation genetic diagnosis, or PGD, allows doctors to screen embryos to see if the child will have any genetic defects before the embryos are placed into a woman’s uterus for pregnancy. If doctors find anything abnormal, they use In Vitro Fertilization to create babies in ‘test tubes’ and they will insert new genes and DNA in a special laboratory (What is a…). Many parents choose this option because if they discover that their child could have a genetic disease, they will replace the faulty DNA with healthy DNA so the child does not contract the disease or illness (What is a…).
Prenatal Screening
1488 Words | 6 PagesFarmers and ranchers have been manipulating genes for plants and animals well before gene sequencing and molecular techniques were practiced. The size of a grapefruit and coloring on cattle may be attributed to the former. With new knowledge about animal and plant genomes, scientists can now delicately screen, edit, and splice genes for varying reasons. This paper intends to explore some of the more common techniques in genetic engineering (prenatal screening, gene manipulation, and cloning) for humans and the ethical issues surrounding them. Genetic technique and screening has entered the medical scene in numerous countries.
Argumentative Essay On Human Genes
475 Words | 2 PagesThe human body has 20,000-25,000 individual genes and the question has arisen of who owns those genes. While having a patent for part of the human genome is different than owning those genes, it has some of the same implications. Thus, the question arises should human genes be patented, and what are the various implications of patenting genes and DNA? Finding a solution to whether the human genome should be patented can be difficult because it requires balancing moral, social, technological, academic, and economic concerns. Even more than that, these concerns need to be addressed in several areas such as naturally occurring DNA, non-natural or lab-synthesized DNA, as well as treatments based on the patients’ genetics.

Ethical Issues In Health Care
2566 Words | 11 PagesReduction of uncertainty Both parents and children may be anxious about their uncertain future. Genetic testing, even if confirming the presence of disease, may remove the uncertainty and allow parents the opportunity to confront the issues directly. When test results are favorable, psychological benefits may accrue to both parents and children. 2.
Pro Genetic Engineering Argumentative Essay
456 Words | 2 PagesMutation in children is not uncommon and it has caused many children to be robbed of the chances that healthy children are born with. A parent blessed with the gift of a healthy child wouldn’t be able to understand the relief genetic engineering would be able to bring to parents of children born with haemophilia, cystic fibrosis, or muscular dystrophy. Not only would choosing the best traits in an organism be good for humans, but for animals and plants. As previously mentioned, plants would benefit in the sense that they will be able to get immunity to pests and their own types of diseases. Animals would be able to make their prime state by modifying their DNA.
Genetic Testing Effects
815 Words | 4 PagesThe Effect of Genomic Testing on Families and Individuals Genetic testing has given scientists and doctors much knowledge into the way disease processes work and has improved the efficacy of treating them. While there are many positive outcomes with genetic testing, there are also some negative ways families and individuals can be impacted. Some ethical dilemmas involving family and genetic testing are: should newborn testing be mandatory or voluntary, do parents have the right to make the decision to have his/her child get genetic testing in adolescent and adult onset conditions, and is the risk to benefit ratio balanced with these tests (Holaday, 2004). In newborn genetic screening the main issue is whether it should be a voluntary
Genetic Testing In Family Care Essay
557 Words | 3 PagesBecause they often do not have access to recorded family health history, many adoptees do not know what diseases could be lurking in their DNA, the inherited genetic material that defines the characteristics of living organisms. With the advent of the Affordable Care Plan and its no-cost preventive care services, many people with known family health histories of hereditary disease can receive genetic testing if they meet generational requirements, such as instances of disease within close familial relationships. However, many adoptees face a unique problem in that they may not know who their parents and extended family are, much less any significant details of their family health history. Considering the obstacles that adoptees and orphans face under these circumstances, genetic testing should be provided to these individuals who have no knowledge of their family health history at no cost under the Affordable Care Act, its successor, or an
The Pros And Cons Of Genetic Engineering

Pros And Cons Of Genetic Testing
896 Words | 4 PagesHave you ever heard of the term genetics? How about genetic testing? If you haven’t even a clue as to what these two terms mean, I’ll dive into it with a brief summary. Genetics itself is the study of heredity and the variation of inherited characteristics, while genetic testing is the sequencing of human DNA in order to discover any genetic differences, anomalies, or mutations that may prove to be pathological. Genetic testing is usually conducted by a medical professional, such as a genetic counselor, though that isn’t the case anymore.
