A student of biology who specializes in genetics, the science of genes is termed a geneticist. A geneticist studies how different characters are innate from generation to generation and what makes the distinction of one method of natural life from the other. A geneticists can engage themselves as a researcher, lecturer or even as a medical doctor. The doctors who specialize themselves in the subject of genetics tries to find out different types of hereditary deformities that can be seen in a newly born child or even before birth of the child and also try to find out effective remedies to overcome such deformities. The problems arising out of various genes are studied by geneticists and then the corresponding patients are referred to better and advanced treatment. Infertility as well as multiple miscarriages is some of the examples of genetic disorders that can be detected and treated. Thus by studying the genes of different patients the geneticists can make out the genetic problems the patient is suffering from and can find out a better treatment for such disorders. Most of the genetic problems arise due to the transformation one gene or amalgamation of character genes. Some of the geneticist centralizes their study on separating such types of genes even though the actual cause of such a situation is not known. Some families exist which suffer from the background of genetic disorders. Genetic counselling is given to such family members by the geneticists. By analysing the information of family history through genetic counselling, the possibility of such genetic disorders in the future generation is detected. The geneticists have variety of opportunities in the field of medicine, general sciences, natural world, farming, and others.
