Personality Traits and Behavioral Genetics

Behavioral Genetics

Research techniques studying genetic and environmental influences.

Family Study

Examines traits across generations in families.

Twin Study

Compares similarity rates in identical and fraternal twins.

Adoption Study

Compares traits of biologically related individuals raised apart.

Heritability

Extent to which genetics influence personality traits.

Molecular Genetics

Study of gene structure and function at molecular level.

Knockout Study

Modifies or removes gene influence in mice.

Epigenesis

Environmental factors that activate or deactivate genes.

Nonshared Environment

Unique experiences that influence individual personality.

Genetic Influence

Role of genes in determining personality traits.

Environmental Factors

External substances affecting gene expression.

Personality Development

Result of gene-environment interactions over time.

Complex Relationship

Interaction of multiple genes and environmental factors.

Genetic Similarity

Humans share 99.9% of DNA across species.

Assumptions in Research

Critiques on twin studies and their categorizations.

Trait Inheritance

Possessing a trait requires gene and environmental exposure.

Research Techniques

Methods used to study genetic and behavioral traits.

Personality Traits

Characteristics shaped by genetics and environment.

Genetic Destiny

Misconception that genes solely determine personality.

Random Factors

Unpredictable elements influencing personality development.

Stem Cell Research

Uses dyes to study gene action in cells.

Genetic Research

Studies identifying genes linked to personality traits.

Behavioral Traits

Observable characteristics influenced by genetics and environment.
