Pre-implantation Genetic Diagnosis (PGD) is a prenatal diagnosis specifically for parents with a high risk of producing an offspring with a serious genetic disorder. This is a socio scientific issue as there are many viewpoints and opinion surrounding this topic. PGD is only permitted if there is a 25% chance of inheritance of the serious condition or if there is a high chance of inheriting chromosome abnormalities which is associated to recurrent miscarriages or advanced maternal age.

are speaking about genes and genetics. We’re also learning about genetic disorders which happen when one person is missing a chromosome or has an extra chromosome. Examples can be Down syndrome or Turner Syndrome. This also relates to punnett squares. In punnett squares you find the probability of characteristics and you can use one to find out the probability of a person developing alcoholism. This article relates to class and can possibly relate to anybody’s life. This article taught me that alcoholism

P2 – Effects of five life factors on individual development Genetic factors such as cystic fibrosis for example‚ are life factors which can affect the development of an individual. It can affect an individual at any age and is caused by a faulty gene that is passed from the parents to the child. The faulty gene allows too much salt and not enough water into cells and makes a build up of thick‚ sticky mucus in the body’s tubes. This can cause blockages in the body’s tubes and passageways‚ and causes

plugged it in the Chi Square to support or reject or hypothesis. This lab was of quite simple procedure and did not require many steps. My calculations were my Chi-Square tests‚ which I am posting here under the discussion box. In this lab‚ I counted the kernels in corn based in color and coat texture. In the hybrid crosses the purple and smooth showed up the most (later on we can see these are the dominant alleles when we plug these values in the Chi-Square test table). If we

Just as genetic testing could be used by employers to spot genetic deficiencies in potential employees‚ it can also be used by insurance companies to screen clients to see if they are genetically prone to specific diseases. The use of such tests is already a reality for life insurance companies‚ which have been given access to genetic test results that indicate whether or not the policy recipient has the genes for Huntington’s disease. Huntington’s disease is of particular interest to life insurance

with a hybrid one out of four of the pea plants were short. Mendel was very confused‚ and kept breeding. After a while‚ Mendel finally discovered how to tell how many plants were going to be tall and short. He figured this out using the punnett square. The punnett square is a little chart that shows which trait your "creation" is going to get. It is a rough estimate‚ but it is better that nothing. Sadly‚ Gregor Mendel’s work was not discovered in his lifetime. Then‚ scientists in the 1900’s proved

The deletion occurs near the middle of the chromosome at a location designated q11.2. 22q11.2 deletion syndrome has many possible signs and symptoms that can affect almost any part of the body. The features of this syndrome vary widely‚ even among affected members
