Genetic Disorders - 1363 Words

Genetic disorders are a topic in biology that can not be avoided. The fact is that genetic disorders can happen in humans, plants or animal. No one and nothing is safe from a genetic disorder. A genetic disorder can appear in the first years off life, or can appear much later in life when least expected. A basic principal of biology states that the behavior of chromosomes during the meiosis process can account for genetic inheritance patterns. There are many reasons for genetic disorders. To start it is important to understand what a genetic disorder is. It is a mutation in the genetic material of a person. The mutant gene is transmitted through birth. These genetic mutations can create serious complications and even death. It is†¦show more content†¦However under certain circumstances their have been cases of people developing the disease from the recessive gene. In simple terms in order for a person to have the disease both parents must have the trait. If only one parent h as the disease there is a chance of the trait being passed on. Huntington disease is a degeneration of the nervous system. It usually occurs in the older part of someone life. As the disease becomes worse it could cause uncontrollable movements in the body. Because the disease causes loss of brain cells, a person can lose memory. It can also contribute to depression. It takes about to ten to twenty years after the first signs of the disease for death to follow. Huntington is a dominant disorder. Children of carriers have a fifty percent chance of inheriting the disease. It is not mandatory for both parents to have the trait for it to be passed on. Huntington is a single gene disorder. Meaning that even if only one parent has the trait the disease can still occur. Alzheimer is on the other hand not a single cell gene disorder. More then one gene mutation can cause this disease. In some cases one gene from each parent is needed in order for the person to get the disease. All offspring in one generation have a fifty / fifty chance of getting this disease. Alzheimer is similar to Huntington in that one loses memory. It usually occurs between the ages of forty and fifty. It currently affects four point fiveShow MoreRelatedGenetic Disorder And Genetic Disorders1351 Words   |  6 PagesA genetic disorder is a disease that is caused by missing or abnormalities in the chromosomes of a human. Finding out if an offspring has a genetic disorder can be determined by using basic genetics. The Punnett Square, a diagram used to predict the results of a crossing or breeding of two species, can determine the outcome of an offspring by using the genotypes of both parents. Pairing the genotypes of both parents together can show the four different genotypes of offspring, two being female, andRead More Genetic Disorders Essay1343 Words   |  6 Pagesnbsp;nbsp;nbsp;nbsp;nbsp;Genetic disorders are a topic in biology that can not be avoided.

One possible cause that can lead to autism is genetic mutations. First of all, families studies indicate that children can affected by autism through heredity. It is true that children inherited some characteristics from their parents. This is because a chromosome of a child produced by one chromosome father and the other one from mother, which formed as DNA. As a matter of fact, if parents have some genetic disease,Read MoreGenetic Disorders and Down Syndrome Essay969 Words   |  4 PagesA genetic disorder is a disease that is caused by an abnormality in an individuals DNA. Abnormalities can range from a small mutation in a single gene to the addition or subtraction of an entire chromosome or set of chromosomes† (Letsou). Most individuals are either related to or know someone who is effected by some ty pe of disability. Many of these disabilities are caused by genetic disorders. Genetic disorders may alter physical appearance and cause mild to severe mental retardation. Fragile XRead MoreThe Genetic Disorder of Down Syndrome1238 Words   |  5 Pagescase of genetic disorder. There are so many all over in the world and many doctors still don’t even know what to call them. Some don’t even know they have a disease in them till its too late, or other know all there lives and some learn to live with the disease and others live every day in fear of getting even more sick and hurt. Genetic disorders are very common some more than others. Its all has to do with our 46 chromosomes. Genetic disorders can occur to anyone. Many people believe genetic disordersRead MoreHuntington s Disease : A Genetic Disorder1121 Words   |  5 Pagesneurodegenerative genetic disorder. It affects the muscle coordination and decline in cognitive that leads to dementia. It affects both males and females in their middle age (J.D, 2015). Huntington’s disease is most common in genetic causes the leads to abnormal involuntary movement also called Huntington’s chorea (J.D, 2015). Epidemiology: Huntington s disease is a rare neuropsychiatric disorder it occurs in a population of 5-10 per 100,000. Huntington disease is a hereditary disorder.

The symptoms of these disorders range from memory loss to blindness, physical abnormalities and more. A process known as gene editing was created in an attempt to do away with genetic disorders. Gene editing was named â€Å"Science Magazine s Breakthrough of the Year 2015† due to its ease and high accessibility (ScienceDirect). It works by using CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) and Cas9 to makeRead MoreGenetic Disorders: Angelman Syndrome866 Words   |  3 Pages A genetic disorder is a mutation in an organisms DNA. It is caused by a change in the sequencing of the nucleotides that make up a specific gene. The genet ic disorder can be inherited by offspring, but it may or may not show in the offspring depending on whether the genetic disorder is a dominate or recessive allele. There are many genetic disorders that humans develop and inherit. Some disorders cause improvements within the human species while others cause severe retardation of the human speciesRead MoreHypercholesterolemia: A Genetic Disorder612 Words   |  2 PagesHuman genetics can play a major role in determining ones physical condition. One slight change in a genetic sequence can cause a disorder that can be life threating to the organism. Most of the genetic disorders are caused by recessive allele. In most cases this recessive allele is undetectable due to the disorder not being presented in the physical appearance. Hypercholesterolemia is an example of a human disorder controlled by a single gene. This human disorder causes high levels of cholesterolRead MoreThe Genetic Disorder : Prader Willi Syndrome1558 Words   |  7 PagesPrader-Willi Syndrome is a genetic disorder that is passed down maternally. The paternal genes of the chromosome 15 in the region of q11-q13 are deleted or unexpressed. The result of these deletions carries distinct phenotypes that differentiate PWS from other disorders (Bà ¶hm, 2014). Some characteristics are a short stature, and specific facial features that tend to make the affected persons resemble one other such as seen in Down syndrome. This typically includes â€Å"almond-shaped eyes, a thin upper
