Medical genetics involves the study of genetics and its applications to medicine. A medical geneticist holds a doctoral degree in genetics (a Ph.D.), and consults with physicians and other medical and dental specialists. The geneticist examines genetic material from blood, tissues or bodily fluids under a microscope, then interprets the test results and passes on the information to doctors and patients regarding genetic problems or issues. Genetic counseling aids those who are concerned with genetic disorders and heredity.
