What molecule carries genetic information in genes?
DNA
What is the influence of heredity on human behavior?
Biological traits, inherited behaviors
What ensures the transmission of traits from parents to offspring?
Genes and DNA
Gene-environment interaction refers to how our genes and environment work together to shape our behavior
Identical twins share all their genes.
True
What is the range of heritability values?
0 to 1
What does the term environment refer to in the context of behavioral development?
External factors influencing development
Stress can interact with genes to affect the risk of anxiety
DNA is a double helix molecule that carries genetic information
What are three examples of environmental factors that influence behavior?
Family dynamics, cultural norms, nutrition
What do twin studies compare to understand the influence of heredity and environment?
Identical and fraternal twins
What is the primary goal of twin studies in understanding traits and behaviors?
Heredity vs. environment influence
High heritability values indicate a strong genetic component for a trait.
True
Match the concept with its description:
Genes ↔️ Basic units of heredity
DNA ↔️ Double helix molecule carrying genetic information
Environmental factors such as education and nutrition significantly influence behavior.
True
Epigenetics studies heritable changes in gene expression that do not involve alterations to the DNA
What is the definition of heredity in the context of behavioral traits?
Genetic information from parents
Genetics can directly influence temperament.
True
What is the definition of environment in the context of behavioral development?
External factors influencing development
Genes can indirectly influence behavior through physical traits.
True
The interplay between biology and experience is crucial in determining who we are.
True
Researchers compare identical twins, who share all their genes, to fraternal twins, who share about half their genes
Heredity shapes our biological traits and behaviors, while environment includes external factors such as cultural norms and nutritional factorsinteractions
Genes can interact with environmental factors to modify behavior, as seen when stress increases the risk of anxiety
