What is a genetic predisposition?
Genetic predisposition is a greater genetic probability of developing certain things, such as diseases, allergies, temperament, a certain level of intelligence or many other examples. It should be noted that people with genetic predispositions do not always end with the things that are predisposed. Although genes can be a reliable predictor of certain elements, environment, or other genes that have not been identified, are also important. People are prone, but they are certainly not expressing genes that have inherited from their parents.
Genetic predisposition should be considered different from genes that are always expressed. Those who inherit the gene for Huntington's disease and eventually show signs of the disease. A woman who carries a gene that suggests that she is more at risk of breast cancer has no same certainty. She has an increased chance to get breast cancer than those in the normal population, but he'll never get it. Some Genes, as well as the one for Huntington, are really not predispositions and they will work instead ifLY inherited, no matter what.
This resolution is important in the analysis of genetic material. It might be necessary to know whether one inherits a serious and/or fatal disease, but there is a fire debate on the question of assessing people by genetic make -up. Genes of family history that indicate higher intelligence, greater risk of heart disease, increased chances of cancer or increased risk of mental diseases are not always guarantees. In addition, people who lack these genetic expressions could still be highly intelligent, more susceptible to heart disease, or are likely to get cancer or mental illness.
The argument of nature/care consists in the core of the debates on the genetic predisposition. The environment plays an important role in the expression of good and bad genes. A person who does not have to be genetically susceptible to mental illnesses in offensive households, but is certainly environmentally prone to this. Smoker very muchincreases the environmental risk of cancer. Even factors like women have their first children and whether breastfeeding can reduce or increase the risk of breast cancer.
One of the concerns about evaluating genetic predisposition by testing genes is that it will be used to distinguish others. Health insurance companies could require genetic testing and pruning from their cylinders anyone who has genes that could indicate an increased risk of disease. Employers could refuse to hire those who might need more time off if they were given specific diseases or could project people more likely intelligence. Countries, such as the US, have signed laws prohibiting discrimination based on genetic factors, but, as with any other form of discrimination, it is still possible to violate or circumvent these laws.
