A genetic predisposition is a genetic effect which influences the phenotype of an organism but which can be modified by the environmental conditions. Genetic testing is able to identify individuals who are genetically predisposed to certain health problems.

[edit] Behavior

Predisposition is the capacity we are born with to learn things such as language and concept of self. Negative environmental influences may block the predisposition (ability) we have to do some things. Behaviors displayed by animals can be influenced by genetic predispositions. Genetic predisposition towards certain human behaviors is scientifically investigated by attempts to identify patterns of human behavior that seem to be invariant over long periods of time and in very different cultures.

For example, philosopher Daniel Dennett has proposed that humans are genetically predisposed to have a theory of mind because there has been evolutionary selection for the human ability to adopt the intentional stance.^[1] The intentional stance is a useful behavioral strategy by which humans assume that others have minds like their own. This assumption allows you to predict the behavior of others based on personal knowledge of what you would do.

[edit] Genetic discrimination in health insurance

The Genetic Information Nondiscrimination Act, which was signed into law by President Bush on May 21, 2008, prohibits discrimination in employment and health insurance based on genetic information.
