What is genetics?
Genetics is the study of DNA, genes, and heredity. It examines gene development, structure, and function in all kinds of living organisms. Plants, animals, humans, and bacteria are all studied as a part of genetics. This branch of biology aims to answer questions about how and why specific characteristics of a species are passed from one generation to the next.

Genetics course curriculum
A genetics course can introduce learners to the basics of biochemistry, molecular biology, recombinant DNA, genomics, and traditional medicine. Depending on the course’s focus, a learner could study topics such as:
The structure of DNA
Methods for packaging DNA into the cell
Genotypes and phenotypes
The Central Dogma of molecular biology, or the conversion of DNA to RNA to protein
Genetic models and tools that predict the breeding value of animals
The dissemination of genetic progress in different animals
Learners can also research genetic disorders and genetic mutation, and examine the technology that is used to predict and help avoid illness in humans.
Careers in genetics
Experts in genetics can work in many different fields and industries. The day-to-day life of a genetics professional varies. For example, a medical geneticist will spend their time diagnosing and treating genetic disorders or conditions while a research geneticist will study those same disorders.
