Genetic Disorders Genetic Screening
1,892 wordsBiology II 10 / 3 / 00 Earths inhabitants have populated all of the regions of the world, discovered places never dreamed of, and have advanced beyond normal understanding, while man can still be conquered by an object which is immeasurably small. While man has been so busy trying to find a way to get rid of all pain and suffering, he has finally discovered that there are things that cannot be stopped. This relentless phenomenon is called a genetic disorder. A genetic disorder by definition is a...

Tay Sachs Genetic Disorder
590 wordsThe genetic disorder I have looked at in this scientific statement is Tay-Sachs disease or TSD, a serious, inherited fatal brain disorder. The disease is named after Warren Tay, a British ophthalmologist who first described the disease in 1881 and a New York neurologist, Bernard Sachs; who first described the cellular changes and the genetic nature of the disease in 1887. This rare hereditary disease is caused by a genetic mutation that leaves the body unable to produce an enzyme; a protein that...

Duchenne Muscular Dystrophy Muscular Dystrophy Association
745 wordsMuscular Dystrophy Scientists have been struggling with the cause, treatment of, and cure for Muscular dystrophy since its discovery in 1886, by Dr. Guillaume Duchenne. Muscular dystrophy is a hereditary disease, affecting thousands of people every year, two-thirds being children between the age of birth through adolescents. However, Muscular dystrophy can occur with no family history of the disease. Muscular dystrophy is a degenerating disease, in which the skeletal muscles degenerate, lose the...

Tay Sachs Disease Sickle Cell Disease
663 wordsEach year a number of children are born with biological defects that impair normal function. For THREE of the following conditions, discuss such aspects as the biological cause, the methods of treatment and possible means of detection and / or prevention. One lethal disorder inherited as a recessive allele is Tay-Sachs disease. This is caused by a dysfunctional enzyme that fails to break down brain lipids of a certain class. The symptoms usually become manifest a few months after birth. Some sym...

Cystic Fibrosis Autosomal Recessive
1,073 wordsCystic fibrosis is a debilitating disease facing many people today. At the present time there is no cure available. According to the cystic fibrosis foundation of America, cystic fibrosis can be traced back as early as 1595. The first documented case was not reported until 1936. One group of people that seem to be affected the most by cystic fibrosis is Caucasians. Recent statistics indicate that 1 in 3, 200 live caucasian births are afflicted with cystic fibrosis. For reasons that are currently...

Factor Viii Clotting Factor
878 wordsAccording to the dictionary Hemophilia is a hereditary disorder in which the blood fails to clot normally, causing prolonged bleeding from even minor injuries. This is only the very basis of this disorder. First of all there are two kinds of Hemophilia. Hemophilia A and Hemophilia B. Hemophilia A is caused by lack of protein factor VIII and is found in 80 % of hemophiliacs. Other names for this are classical hemophilia, factor VIII deficiency hemophilia. Hemophilia B is caused by a deficiency of...

Amniotic Fluid Sound Waves
1,514 wordsChildhood is the culturally defined period in human development between infancy and adulthood. In a historical perspective, this is a relatively new social construction. Early childhood, as an especially important super period of childhood, most often refers to the months and years between infancy and school age children (Corsini 345). To understand why childhood is such a crucial time in human life it is important to study the development before and after birth along with any factors that may a...

Factor Ix Clotting Factor
1,179 wordsIntroduction Hemophilia is a rare genetic blood clotting disorder that primarily affects males. People living with hemophilia do not have enough of, or are missing, one of the blood clotting proteins naturally found in blood. Two of the most common forms of hemophilia are A and B. In persons with hemophilia A (also called classic hemophilia), clotting factor VIII is not present in sufficient amounts or is absent. In persons with hemophilia B (also called Christmas disease), clotting factor IX is...

Law Of Segregation Recessive Allele Alleles
336 wordsGregor Mendel played a huge role in the underlying principles of genetic inheritance. He grew up in a Augustinian brotherhood where he learned agricultural training with basic education. He then went on to the Olmutz Philosophical Institute and then entered the Augustinian Monetary in 1843. After 3 years of theological studies, Mendel went to the University of Vienna where he was influenced by 2 professors, the physicist Doppler and a botanist named Unger. Here he learned to study science throug...

Color Blindness Ed
709 wordsColor Color Blindless Color Blindless Color blindness is the inability to distinguish particular colors. It is generally an inherited trait, but can result from a chemical imbalance or eye injury. There are three primary colors. They are red, blue, and yellow. All other colors are the results of different combinations of primary colors. Special visual cells, called cones, are respon-sible for our ability to see color. People with normal vision have three different types of cones, each responsibl...

Autosomal Recessive Autosomal Dominant
1,092 wordsEhlers-Danlos syndrome (EDS) is a rare inherited group of connective tissue disorders characterized by defects of the major structural protein in the body (collagen). Collagen is a tough fibrous protein that plays an essential role in binding, holding together, strengthening, and providing elasticity to bodily cells and tissues. There are six major types of EDS that I will discuss, however I will only go into detailed discussion on two of the six types of EDS. The two major types of EDS are Clas...

Genetic Disorders Birth Defect
363 wordsGenetic disorders, affecting many different races and genders, have been around for a very long time. Genetic disorders, usually caused by recessive genes, range from minor traits to conditions that prove fatal. Moreover, disorders often result in multiple abnormalities. Furthermore, skeletal and muscular disorders are often transmitted by a single gene, like achondroplasia, a type of dwarfism characterized by abnormal proportions of the arms, legs and body, results from impaired cartilage growt...

Hardy Weinberg Genetic Drift
245 wordsPopulation Hw Lab I. Title Population Genetics and Evolution: Hardy Weinberg Equation II. Hypothesis This lab is separated into four different cases. Within each of these cases, there are aspects that change the allele frequency within a population (this will be more deeply explained in the analysis). The first case represents the Hardy-Weinberg equilibrium. In this case, I hypothesize that the allele frequencies should end up with no alterations from the original frequencies. My hypothesis is b...

Tay Sachs Disease Autosomal Recessive
812 wordsThis condition, Tay-sachs TAY-SACHS DISEASE This condition, Tay-Sachs Disease, is due to the reduction of a key enzyme. This missing enzyme is hexosominidase and is commonly referred to as Hex A. When this enzyme is missing in lipids (fats), GMZ ganglioside accumulates in inert cells. Hex A is key and is needed to break up and regulate lipids. When GMZ builds up in the neurons, the functions of the nervous system are affected. This leads to mental retardation, damages in the nervous system, and ...

The progressive taxation system is most evident in the income taxes; the tax is levied at a rate that increases as the quantity of income i...

Gregor Mendel Second Law
1,343 wordsGregor Mendel was an Augustinian nineteenth century monk who, due to a series of momentous experiments, is now widely regarded as the forefather of genetics. Mendel studied the inheritance of seven contrasting characteristics of the species Pisum sativum, more commonly known as the garden pea. Each of the variables that Mendel experimented with were discontinuous; there were no intermediate forms. For example, one of the variables was length of stem, which was always either tall or short. From h...
