Genetics is the science of information transfer from one generation to another. We learn the laws of inheritance in all creatures big and small, how they evolve and how they change. On the molecular level we learn about DNA and RNA, on the cellular level we discover what makes a cell cancerous, and on an organismal level we examine the reproductive habits of various organisms. Crucial principles include the structure, function, and transmission of genes. Laboratory techniques explore genetic engineering from the "inside." Genetics is crucial to all of biology, hence a genetics major has great flexibility. This is excellent preparation for advanced study in biological sciences, law, genetic counseling, and many health-related professions.
Approximately 25% of biology students proceed directly to graduate school in biology or biology-related fields. About 45% go on to schools of medicine, veterinary medicine, or dentistry. Still others go directly to work in a broad variety of fields. These include research or applied science positions in biotechnology, pharmaceutical, and chemical industries. Some become high school teachers, go into sales, or work for governmental regulatory agencies, zoos, or parks.
