Genetics intersects almost every other field of biology. For this reason, professionals with a genetics education have a broad range of career opportunities. The recent success of the Human Genome Project has created a great demand for genetics professionals with a variety of expertise in all areas of genetics, not only those applicable to human disease.

Geneticists are involved in identifying genes responsible for basic biological traits, including genes that cause disease or mediate a response to a medication. Geneticists also determine how those genes function in organisms, including plants, animals, and humans. They may treat individuals with a particular genetic disorder or counsel families regarding the genetics of human disease. Geneticists are also involved in identifying genetic mechanisms to improve agricultural processes, such as breeding pest-resistant fruits and vegetables. Geneticists are also interested in the distribution of genetic variations in populations and how those variations arise. Additional...
