Genetics

Genetics is the science that studies genes, inheritance, and variation in organisms. It investigates how genetic information is passed from one generation to the next and how these genes affect development, growth, health, and disease. Genetics also explores mutations and how changes in DNA can lead to genetic disorders such as cystic fibrosis or Down syndrome.

This field plays a crucial role in understanding many biological processes, such as hereditary diseases, evolution, and in applications like genetic engineering, personalized medicine, and biotechnology.

Geneticists or genetic counselors help patients understand their genetic risk for certain diseases and provide guidance on genetic testing and treatment options.
