Genetic Influence on Behavior and Environmental Interaction

Very Hard Unit 2: Biological Bases Genetics And Behavior

Researchers in behavioral genetics often explore how specific genetic markers are associated with particular psychological traits. A recent study has identified a gene variant that appears to correlate significantly with increased levels of aggression in individuals. This discovery raises important questions regarding the ethical implications of genetic predispositions in relation to behavior and personal accountability. When considering the broader implications of genetic influence on behavior, which of the following statements most accurately reflects our current understanding of this relationship?

Individuals with the identified gene variant are destined to be aggressive regardless of environmental factors.

Genetic influence on behavior is deterministic, leaving no room for individual choice or environmental impact.

Identifying genetic markers can help predict behavior, but environmental factors can significantly modulate these traits.

Behavioral genetics suggests that the environment overrides any genetic predispositions.

All aggressive behavior is solely a result of genetic makeup, independent of environmental influences.
