Nature vs. Nurture: This term refers to the ongoing debate about whether our traits and behaviors are primarily influenced by genetics (nature) or by environmental factors such as upbringing and experiences (nurture).
Gene-environment interaction: This term specifically focuses on how certain genes may be more influential in certain environments, highlighting that genetic effects can vary depending on environmental circumstances.
Epigenetics: Epigenetics is the study of changes in gene expression or cellular phenotype without alteration of DNA sequence itself. It explores how environmental factors can affect gene activity by modifying chemical marks on DNA, influencing whether certain genes are turned 'on' or 'off.'
