A behavioral geneticist is a scientist who studies the role of genetics in shaping behavior and traits. They investigate how genes and environmental factors contribute to individual differences.
Heritability refers to the proportion of variation in a trait that can be attributed to genetic differences among individuals.
Twin studies: Twin studies are research studies that compare similarities between identical twins (who share 100% of their genes) and fraternal twins (who share about 50% of their genes) to determine the relative contributions of genetics and environment on a particular trait.
Gene-environment interaction: Gene-environment interaction refers to the interplay between an individual's genetic makeup and their environment, where genes can influence how individuals respond or adapt to different environmental conditions.
