Examples of behavioral genetics in the following topics:
-
- The influence of genes on behavior has been well established in the scientific community.
- To a large extent, who we are and how we behave is a result of our genetic makeup.
- While genes do not determine behavior, they play a huge role in what we do and why we do it.
- Behavioral genetics studies heritability of behavioral traits, and it overlaps with genetics, psychology, and ethology (the scientific study of human and animal behavior).
- Genetics plays a large role in when and how learning, growing, and development occurs.
-
- Behavior can influence genetic expression in humans and animals by activating or deactivating genes.
- Behavior can have an impact on genetic makeup, even as early as the prenatal period.
- It is important to understand the implications of behavior on genetic makeup in order to reduce negative environmental and behavioral influences on genes.
- Addiction is thought to have a genetic component, which may or may not be caused by a genetic mutation resulting from drug or alcohol use.
- Light exposure also influences genetic expression.
-
- The biological perspective on personality emphasizes the influence of the brain and genetic factors on personality.
- This research can include the investigation of anatomical, chemical, or genetic influences and is primarily accomplished through correlating personality traits with scientific data from experimental methods such as brain imaging and molecular genetics.
- The field of behavioral genetics focuses on the relationship between genes and behavior and has given psychologists a glimpse of the link between genetics and personality.
- A large part of the evidence collected linking genetics and the environment to personality comes from twin studies, which compare levels of similarity in personality between genetically identical twins.
- In the field of behavioral genetics, the Minnesota Study of Twins Reared Apart—a well-known study of the genetic basis for personality—conducted research with twins from 1979 to 1999.

- According to evolutionary psychology, individuals are motivated to engage in behaviors that maximize their genetic fitness.
- The basic idea of evolutionary psychology is that genetic mutations are capable of altering an organism's behavioral traits as well as its physical traits.
- In this way, individuals are motivated to engage in behaviors that maximize their genetic fitness.
- This results in social processes that maximize individuals' genetic fitness, or ability to pass their genes to the next generation.
- Evolutionary psychology suggests that individuals are motivated to engage in behaviors that maximize their genetic fitness.
-
- DNA, or deoxyribonucleic acid, determines whether our eyes are blue or brown, how tall we will be, and even our preference for certain types of behavior.
- Some genetic traits are linked to a person's sex and therefore passed on by the sex chromosomes.
- The autosomes contain the remainder of a person's genetic information.
- Chromosomal and genetic manipulation are controversial topics.
- By studying chromosomes and genes, scientists are able to determine the genetic basis for many diseases.
-
- Although environment also plays an important role, genetics influence human intelligence and our capacity to learn in many ways.
- While environmental influences play a large role, our ability to learn is also largely shaped by genetics.
- One of the most extensively studied behavioral traits is intelligence.
- The occurrence of neurobehavioral disorders is influenced by both genetic and non-genetic factors, and the genes directly associated with these disorders are often unknown.
- Discuss the role genetics play in our cognition and our ability to learn.
-
- The environment in which a person is raised can trigger the expression of behavior for which a person is genetically predisposed, while the same person raised in a different environment may exhibit different behavior.
- When the children's own genotype influences their behavior or cognitive outcomes, the result can be a misleading relationship between environment and outcome.
- It is relatively unclear whether the genetic or environmental factors had more to do with the child's development.
- Evocative gene-environment correlation happens when an individual's (heritable) behavior evokes an environmental response.
- Identical twins share the same genotype, meaning their genetic makeup is the same.
-
- The biopsychosocial model argues that any one factor is not sufficient; it is the interplay between people's genetic makeup (biology), mental health and behavior (psychology), and sociocultural environment (social world) that determine the course of their health-related outcomes.
- Biological influences on health and illness and include genetics, infections, physical trauma, nutrition, hormones, and toxins.
- Many disorders have an inherited genetic vulnerability.
- Alternatively, psychological factors may exacerbate a biological
predisposition by putting a genetically vulnerable person at risk for
other risk behaviors.
- Specifically, research on epigenetics suggests that the environment can
actually alter an individual's genetic makeup.
-
- Human intelligence is shaped by both internal genetic factors and external environmental circumstances.
- While extreme genetic or environmental conditions can predominate behavior in some rare cases, these two factors usually work together to produce individual intelligence.
- However, certain single-gene genetic disorders can severely affect intelligence.
- And like most traits, the occurrence of neurobehavioral disorders is influenced by both genetic and non-genetic factors, and the genes directly associated with these disorders are often unknown.
- Biological influences act on the physical body, while sociocultural influences shape the mind and behavior of an individual.
-
- Developmental psychology seeks to understand the influence of genetics (nature) and environment (nurture) on human development.
- Natural human behavior is seen as the result of already-present biological factors, such as genetic code.
- Nurtured human behavior is seen as the result of environmental interaction, which can provoke changes in brain structure and chemistry.
- Some concrete behavioral traits are dependent upon one's environment, home, or culture, such as the language one speaks, the religion one practices, and the political party one supports.
- The diathesis–stress model is a psychological theory that attempts to explain behavior as a predispositional vulnerability together with stress from life experiences.
