What is a Genetics Degree?
Genetics is concerned with how traits such as hair color, eye color, and risk for disease are passed or inherited from parents to their children, and how these inherited traits differ from person to person.
At the center of the study of genetics is the genetic code or ‘genome.’ This genetic information is made up of a chemical called deoxyribonucleic acid (DNA) and is stored in almost every cell in the body. Every human genome contains 20,000 genes. The human body contains between 75 and 100 trillion cells. And every human cell contains 46 chromosomes that provide the genetic instructions for a body to live, grow, and develop.
These numbers alone speak to the complex work of geneticists and to the fascinating subject matter tackled by students of genetics.
Bachelor’s Degree in Genetics – Four Year Duration
The typical Bachelor’s Degree in Genetics is designed as a stepping stone to further study at the graduate level. Career opportunities in the field for undergrads are decidedly limited, normally to laboratory assistant jobs.
The bachelor’s curriculum is founded on courses in biochemistry, molecular chemistry, microbiology, physics, mathematics and statistics, botany, zoology, and of course introductory level genetics. Here is a snapshot of a typical program:
- Introductory Applied Statistics for the Life Sciences – introduction to modern statistical practice in the life sciences; exploratory data analysis, probability, and random variables; one-sample testing and confidence intervals, role of assumptions, sample size determination, and two-sample inference; experimental design, analysis of variance, linear regression, and goodness-of-fit; biological applications
- Introductory Organic Chemistry with Laboratory – fundamental aspects of organic molecular structure, including stereochemistry; basic themes in organic reactivity

- Plant Genetics – the basic concepts of genetics and genomics as applied to plants; the course objective is to provide students with an understanding of the principles and methodologies of plant genetics so that they can adopt them in their research projects
- Cancer Genetics – introduction to the genetic and epigenetic alterations in cancer; DNA sequencing of human cancers; major issues in cancer research; evaluating cancer genetics literature
- Plant Cell Culture and Genetic Engineering – theoretical and practical training in plant cell and tissue culture, and plant genetic engineering
Master’s Degree in Genetics – Two Year Duration
Genetics graduates with a master’s degree are prepared for careers in science and/or health. Opportunities exist in laboratory / research and academic settings or in the field of genetic counseling, which is focused on providing information and support to families who have members with birth defects or genetic disorders and to families who may be at risk for a variety of inherited conditions.
To work as a genetic counselor requires graduation from a program accredited by the American Board of Genetic Counseling. Coursework for master’s students is typically undertaken in the first year of the program. The second year is dedicated to research activities in laboratory genetics or genetic data analysis, leading to the development of a thesis project.

Doctoral Degree in Research Genetics – Five to Six Year Duration
Doctoral Degree in Medical / Clinical Genetics – Six Year Duration
At the doctoral level, two kinds of programs are offered. The first is targeted at students who want to become research geneticists. As the name suggests, these scientists conduct genetic research and development. They defend a dissertation topic and earn a Ph.D. in the field. Their training also includes laboratory rotations, coursework in teaching theory, and a teaching practicum.
The second option is for those who wish to pursue careers as medical or clinical geneticists, who diagnose and treat genetic diseases including inherited diseases like hemophilia, and diseases causes by DNA alterations, such as familial breast cancer, leukemia, and lymphoma.
These practitioners work at the intersection of research and medical care. After earning a bachelor’s degree, they must graduate from an accredited medical school with either a Doctor of Medicine (MD) degree or a Doctor of Osteopathic Medicine (DO) degree. Following completion of med school, they must complete a two-year residency in clinical genetics and genomics. In addition to the clinical genetics certification, the American Board of Medical Genetics also certifies physicians in:
- Clinical Biochemical Genetics – a graduate certified in biochemical genetics directs and interprets biochemical analyses relevant to the diagnosis and management of human genetic diseases, and acts as a consultant regarding the laboratory diagnosis of a broad range of biochemical genetic disorders
- Laboratory Genetics and Genomics – a graduate certified in laboratory genetics and genomics directs and interprets both clinical cytogenetic and molecular genetic analyses relevant to the diagnosis and management of human genetics diseases, and act as consultants in laboratory diagnoses for a broad range of molecular and chromosomal-based disorders, including both inherited and acquired conditions
While the two genetics educational tracks are decidedly different, they are of course inextricably intertwined. Genetics medicine and counseling are guided by the discoveries of genetics research, which in turn is driven by the evolving needs and challenges faced by the clinical field it serves.
Here is an overview of some doctoral level genetics coursework common to both the medical and research tracks:
- Medical Gross Anatomy
- Neurobiology of Learning and Memory
- Experimental Design and Statistical Methods
- Neurobiology of Aging
- Clinical Anatomy
- Professional Skills for Students in the Biomedical Sciences
- Developmental Cognitive Neuroscience
- Methods in Neuroscience

Degrees Similar to Genetics
The focus of biochemistry is the chemical processes and reactions that occur in living matter. Biochemists apply principles of both biology and chemistry to issues in many different sectors, including the environment, medicine and health, industry and manufacturing, agriculture, biofuels, and marine science.
Simply stated, biomedical engineering uses engineering to solve health and medical problems. For example, a biomedical engineer might look for chemical signals in the body that warn of a particular disease or condition.
Majors in this field study engineering and the life sciences to create new products – such as vaccines, medicines, growth hormones for plants, and food additives – for the agricultural, industrial, and environmental industries. Among typical classes are biochemistry, general biology, cell biology, chemistry, and genetics.
Botany is the study of the physiology, structure, genetics, ecology, distribution, classification, and economic importance of plants. Degree programs in the field include courses in biochemistry, microbiology, photosynthesis, and plant evolution.
Chemistry is the science that deals with identifying the substances that make up matter. Degree programs in chemistry focus on investigating these substances: their properties; how they interact, combine, and change; and how scientists can use chemical processes to form new substances.
Cytotechnology is the study of cells and cellular anomalies. Cytotechnologists use a microscope to examine slides of human cells to uncover evidence of abnormalities that may reveal inflammation, infection, or disease.
Epidemiology, a fundamental science of public health, is concerned with health and disease at the population level; that is to say, within groups or communities. Its focus is the frequency, pattern, causes, and risk factors of diseases and other health-related events within these specified populations, which range from neighborhoods and schools to cities, states, countries, and the world at large.
Epidemiologists – often referred to as disease detectives – are the scientists and investigators whose work begins with looking for clues by asking questions. Who is sick? What are their symptoms? When did they get sick? Where could they have been exposed? Using statistical analysis, epidemiologists study answers to these questions and produce data that lead them to identify how a particular health problem was introduced, how its spread can be controlled, and how it can be prevented.
Forensic chemistry applies the principle and techniques of chemistry to the testing of evidence from victims and crime scenes.
Microbiology is the study of all living organisms that are too small to see with the naked eye. These ‘microbes’ include bacteria, archaea, viruses, fungi, prions, protozoa, and algae.
The field of molecular biology is concerned with genetics, with the structure and the relationships between four molecules in the body: proteins, fats, carbohydrates, nucleic acids.
Pathology is the science of the causes and effects of diseases. Pathologists are the medical doctors who analyze organs, tissues, blood, and body fluids to search for medical conditions and diagnose disease and illness. In other words, their job is to solve often complex medical mysteries.
Pathologists typically do not have direct contact with patients, but they work closely with primary care physicians and other medical specialists. This unique position in medical practice has earned them the moniker of the ‘doctor’s doctor.’
Pharmaceutical science is concerned with the discovery and development of new drugs and therapies. The main categories of the field are drug discovery and design, drug delivery, drug action, clinical sciences, drug analysis, cost effectiveness of medicines, and regulatory affairs.
Zoology students learn about animals, their evolution, anatomy, physiology, and natural habitats. Graduates may be employed by zoos, veterinary clinics, or labs. Their work may involve monitoring and writing reports on animal behavior, analyzing specimens to test for diseases, and/or working in the areas of ecology and conservation.
