Genetic Disorders Essay - 1343 Words

nbsp;nbsp;nbsp;nbsp;nbsp; nbsp;nbsp;nbsp;nbsp;nbsp;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. nbsp;nbsp;nbsp;nbsp;nbsp;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 thru birth.†¦show more content†¦nbsp;nbsp;nbsp;nbsp;nbsp;Common recessive diseases are cystic fibrosis, sickle cell anemia, Tay Sachs. Alzheimer and Huntington diseases are examples of dominant disorders. Some mutant disorders occur on the X chromosome. Females have little or no effects if the mutation occurs on the X linked gene. Males on the other hand do not have another X chromosomes so do not have another gene to fall on. Dominant disorders linked to the X chromosomes are usually very deadly to males. These disorders tend to affect men more then women. Almost exclusively. Some of the diseases associated with the X are down syndrome, Hemophilia. There are also the diseases that occur on the sex genes. They also come in recessive and dominant forms. With this it determines who will get the disease. For example a mother can pass on a trait to a daughter but not to a son and vice versa. nbsp;nbsp;nbsp;nbsp;nbsp;One can not forget that genetic disorders can also occur because of external effects. Things like cigarette smoking and drinking during pregnancy can affect the babies genetics. Leaving the baby with one of the genetic disorders. nbsp;nbsp;nbsp;nbsp;nbsp;Sickle cell anemia is a genetic disorder that usually appears between the ages of 2 and 4 years old. The red blood cells are shaped like crescents or sickles. The red blood cells only last about 10 to 24 days. In a healthy person they last about 120 days. That is where the anemia part of the name comes into play.

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 MoreGenetic Disorders1363 Words   |  6 PagesGenetic disorde rs 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 type 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
