Not long ago, genetics was a highly specialised field, progressed by a specialised group of researchers called geneticists. Now it is the foundation for studies in all the biological sciences.
At its core, genetics is the study of the variation between living things and how this variation is inherited. This can include studies of gene regulation, development, neurogenetics, population genetics and evolution along with genetic disease detection, prevention and treatment in humans, animals and plants.
This knowledge is then applied to research in biology, biomedical sciences, biotechnology, ecology and conservation.
