Heritability:Heritability is the extent to which individual differences in a trait can be attributed to genetic factors. It measures how much variation in a trait is due to genetics rather than environmental influences.
Twin Studies:Twin studies involve comparing similarities between identical (monozygotic) twins and fraternal (dizygotic) twins to determine the relative contributions of genetics and environment on specific traits or characteristics.
Gene-environment interaction: This term refers to the interplay between an individual's genes and their environment, where both factors influence each other in shaping an individual's personality or behavior.
