The possessor of this genotype has the genetic disorder called Down syndrome. Down syndrome is caused by this person having chromosome 21, which is also called Trisomy 21. There are different things you see in people with Down syndrome such as, different physical and mental traits. This genetic condition varies between each person with this genetic disorder. They all have similar features, but do not look the same.
Down syndrome was fist described by John Langdon Down in 1866, but the earliest depiction of someone with Down syndrome was a painting dated in 1515. John Langdon Down had said it was only a disorder, but did not understand how it occurs. The cause was later discovered in 1959.

The two types of tests are Screening tests and the Diagnostic test. The Screening test is done with an ultra sound or a blood tests when the woman is in her first or second trimester. The Diagnostic test has two options such as chorionic villus samplingor amniocentesis. These two tests detect anything wrong with the fetus. The doctor can also tell if it has Down syndrome when the baby is born based on how it looks and after its physical exam. The doctor takes a blood test to make sure the baby has Down syndrome or not. The blood test can take a couple of weeks to get the results. According to Down Syndrome Education International,” Worldwide, we estimate that 220,000 babies are born every year with Down syndrome.”(Down Syndrome Education International, …show more content…
Research has said that this random occurrence has nothing to do with the activity from the mother or father or the environment. National Institutes of Health says, “In more than 90% of cases, the extra copy of chromosome 21 comes from the mother in the egg. In about 4% of the cases, the father provides the extra copy of chromosome 21 through the sperm. In the remaining cases, the error occurs after fertilization, as the embryo grows.” (National Institutes of Health, 2012.”
There are specific things to look for in people who have Down syndrome. According to WebMD, things to look for are, “Distinctive facial features, such as a flat face, small ears, slanting eyes, and a small mouth. A short neck and short arms and legs. Low muscle tone (hypotonia) and loose joints. Muscle tone usually improves by late childhood. Below-average intelligence.” (WebMD, 2005.) They do not all look alike. Some may have different shaped features such as, different eye shape, nose shape, head shape, or mouth. Many children with Down syndrome tend to look like their mother or
Down Syndrome affects many people, even those who don’t have it. Down syndrome is also called Trisomy 21. The term Down syndrome did not become the accepted term until the early 1970’s (“History of NADS”). Down syndrome is the most common genetic condition, almost 400,000 Americans have Down syndrome (“What Is Down Syndrome?”). When the 21st chromosome has an extra copy, full or partial, down syndrome will occur. With the extra genetic material it messes with the development physically and mentally. It also creates certain features connected with Down Syndrome. Some of the well known features are low muscle tone, small stature, upward slant to the eyes, and a single deep crease across the center of the palm (“What Is Down Syndrome?”). These features and their extent can vary from person to person, some may not even have any at all. One in every 691 babies born in the United States has Down syndrome, about 6,000 babies are born with Down syndrome each year in the United States (“What Is Down Syndrome?”). Just like the physical features the medical problems associated with Down syndrome vary from person to person, some may need a lot while others may need little to none. The health problem can be treated with the many resources available to help the people with Down syndrome and their families.
In Otto Dix’s “Shock Troops Advance Under Gas”, Dix presents the brutality of war for everyone to see. From the barbed wire snagging a troop’s arm to the gas masks, this work illustrates true horror. Dix’s illustration of war helps display that war truly is not something to write home about with pride. Thus, I present the argument that war is not something to be patriotic over, and it is not something we should be thanking the troops for. They are brave individuals, but the duties they perform are not – they are the product of cowardly nations. The purpose of this paper is to convey my personal feelings towards this work, war and how it is not the answer, and tying in my visit to the McNay Art Museum back to aspects of war.
Every normal person inherits one copy of chromosome 21 from father and one copy of chromosome 21 from mother thus they have two copies of chromosome 21. But individuals with Down syndrome have 3 copies of chromosome 21. According to the Centers for Disease Control and Prevention (2014), one in every 700 babies is born with Down syndrome in the United States. Due to this
a child who doesn´t. When a child has down syndrome there are very noticeable symptoms like: flattened facial features, short neck, small head or poor muscle tone . Some other symptoms that could be present are: more flexibility than a healthy person would have, brushfield spots which are tiny dots on the iris of the eye or unusually shaped ears. Although babies with Down syndrome seem to be the same size as normal babies, they end up growing slower causing some of the unusual formalities. Also things like walking or sitting can happen at a later age than usual for kids with this genetic disorder (3). Not only are there physical symptoms that are easier for us to notice but there are also health problems that can occur with this disorder as well. Babies who have Down syndrome are likely to have health problems like: mild to moderate cognitive disabilities, heart defects, depression or behavior problems and many others
Down syndrome is a genetic disorder in which a person is born with an extra copy of chromosome 21. There are three genetic variations that cause Down syndrome: Trisomy 21, Mosaic Trisomy 21 or Translocation Trisomy 21. There are many ways in which theses disorders affect the body. Trisomy 21 occurs when an egg or sperm comes in with an extra copy of chromosome 21, then, once an embryo is formed and starts to develop, the chromosome is replicated in every single cell of the embryo. Trisomy 21 is the most common type of Down syndrome. About 92% of Down syndrome patients have this type. People with Trisomy usually have physical problems.

Various test can be done in order to see if the foetus has Down Syndrome. The most common tests to look for Down Syndrome.
Bipolar Disorder is a mental illness that has many effects on the human body and mind. It’s found in young adults and children as well. Statistics show that the disorder affects about four million people in the United States and is becoming one of the most common disabilities in the United States today. People with bipolar disorder undergo two types of mood swings: depression and mania. Those two are then divided into subcategories: Bipolar 1 Disorder, Bipolar 2 Disorder, and Cylothymia. This paper will discuss bipolar disorder, the subtypes and the symptoms, as well as causes and treatments.
Down syndrome is also called 21 trisomy, which is obviously pointed out the disorder occurs at the chromosome 21. Genetically, it has been found that there are 22 pairs of autosomes and one pair of sex chromosomes, where X and Y are sex chromosomes representing female and male respectively. These two kinds of chromosome pairs are normally made up 46 chromosomes in total while children with Down syndrome have 47 chromosomes, meaning they have one extra chromosome on the chromosome 21. This chromosomal disorder happens occasionally and randomly. One cannot put blame or fault on the individual or parent when the gene is
Do you ever see other people and wonder why they act and look so differently? Their is a genetic disorder by the name of Down-Syndrome. Down-Syndrome is a condition in which a person has 47 chromosomes while others have 46. People with this disorder may have the facial features of flat face, small nose, upward slant eyes, enlarged tongue and may appear shorter than others. Down-Syndrome has nothing to do with race, nationality, religion or anything the father or mother did during pregnacy.. Most parents want to know what is going on with the baby as the mother is pregnant and the best way to find out if your child is diagnosed with Down-Syndrome is a screening test and diagnostic test. A screening test is when you take a blood
Some symptoms of Down Syndrome is short neck, flattened facial profile and nose, can have a small head, ears, and mouth, wide short hands with short fingers, and white spots in the color part of the eye. They may have poor judgement, impulsive behavior, and delayed language and speech development. When a child has down syndrome, the physical development is slower than a normal child. It will take kids with down syndrome longer to learn how to sit, walk, and talk rather than a child with no down syndrome. (https://www.nichd.nih.gov/health/topics/down/conditioninfo/symptoms)
Down syndrome is a chromosomal condition related to chromosome 21. Down syndrome is a defect in the chromosomes causing intellectual impairment. Down syndrome is a very serious and sad disease but some people have said that it has brought more love into their home.
Down syndrome is commonly known by the public as a disease that causes physical and mental disabilities in people. Down syndrome is known by the scientific community as a genetic disorder of the twenty-first chromosome. As a result of this genetic disorder other systems of the body are also affected, this includes mental and physical disabilities. Down syndrome “is a lifelong condition… that happens before birth” (WebMD, 2015). According to the National Down Syndrome Society one in every 691 babies are born with the condition (NDSS, 2015). In order to understand this condition it is
. Down syndrome is not a disease that someone catches and is not caused by difficulties during the pregnancy, it is a genetic condition. This condition is caused by the presence of an extra chromosome in the body’s cells and causes a redundant amount of proteins to be formed. All cells of the body derive from a single cell formed by the fusion of a father’s sperm and a mother’s egg. Each cell carries a nucleus full of genetic material known as genes. These genes are inherited from both the mother and father. Each cell normally contains 46 pairs of chromosomes. 23 chromosomes come from one parent and 23 from the other, hence the 46 pairs. When it comes to children with down syndrome, one of the chromosomes does not separate properly and so the
