All of these are influenced by the interaction of your genesand the environment in which you were 47 . The study of how genes and environmentinteract to influence 48 activity is known as behavioral genetics. Behavioral genetics has madeimportant 49 to the biological revolution, providing information about the extent to whichbiology influences mind, brain and behavior.

　　Any research that suggests that 50 to perform certain behaviors are based in biology iscontroversial. Who wants to be told that there are limitations to what you can 51 based onsomething that is beyond your control, such as your genes? It is easy to accept that genescontrol physical characteristics such as sex, race and eye color. But can genes alsodetermine whether people will get divorced, how 52 they are, or what career they are likely tochoose? A concern of psychological scientists is the 53 to which all of these characteristicsare influenced by nature and nurture(養(yǎng)育), by genetic makeup and the environment.Increasingly, science 54 that genes lay the groundwork for many human traits. From thisperspective, people are born 55 like undeveloped photographs: The image is already captured,but the way it 56 appears can vary based on the development process. However, the basicpicture is there from the beginning.
