Environmental Genetics

Environmental Genetics studies the impact of environmental factors on genetic expression and their role in the development of diseases and traits. It examines how genetic makeup interacts with external exposures like pollutants, diet, lifestyle, and climate, influencing an organism’s health and behavior. This field looks into how environmental factors can trigger genetic changes or affect gene expression through mechanisms like epigenetics, which can modify how genes are activated or silenced without altering the DNA sequence itself. Environmental genetics is essential for understanding complex conditions such as cancer, cardiovascular diseases, and neurodegenerative disorders, which involve both genetic and environmental factors. Additionally, it investigates how populations adapt to environmental changes over time, offering valuable insights into evolution and biodiversity. By exploring these interactions, researchers aim to improve strategies for disease prevention, personalized healthcare, and public health initiatives.
