Genetics is a biology discipline that examines the science of heritability, genes, and the natural variations in living organisms. The rapid development of the field of biotechnology has also incorporated genetics to include genetic engineering and modification of organisms for specific purposes.
This course will introduce you to the field of genetics starting with an introduction to genetics as well as cellular biology. Students then learn about chromosomes, genetic interactions, biochemistry of DNA and chromosomes, mutations, DNA repair and recombination and then finish the course with more applied subjects such as developmental, population and applied genetics.
This course is suitable for:
- plant and animal breeders
- anyone involved with reproduction who needs a deeper understanding of genetics
- anyone interested in this fascinating topic.
- To acknowledge the history of modern genetics and interpret important terminology in genetics work used, specifically relating to areas of study such as plant and animal sciences, conservation of plant and animal species, agriculture, horticulture, veterinary medicine and human health sciences.
- To develop understanding of the structures (organelles) of cells and comprehend their basic functions specifically relating to cell division.
- To discuss the main ways features are inherited.
- To develop knowledge of biological interactions and understand the significance of gene expression in heritability.
- Describe chemicals and reactions involved in genetics including protein synthesis.
- Explain the nature and management of genetic mutations.
- Develop understanding of how DNA repair mechanisms, and recombination to understand the significance of DNA cleaving and re-joining.
- Demonstrate an understanding of genetics to explain how variations occur in living organisms both within and beyond species.
- Explain both the significance and dynamics of genetic variation within populations of different living organisms.
- Describe how genetic knowledge is applied to a variety of human endeavors.

When you have completed the lessons of your Certificate course, you will be given the option of taking the optional exam. It's okay if you don't want the exam, we still issue your Careerline Certificate. For Advanced Certificates however, the exam is compulsory (per module) and are included in the course fee.

Our science courses are taught by a range of different tutors depending on the area of expertise. We have specialised tutors in environmental science, animal (veterinary) science, human nutrition and health science and so on. At enrollment you will be assigned your tutor who is an expert in that field. You will receive a welcome email from them within 1 - 2 days of enrollment so you will be able to contact them as soon as you need to.
Some subjects such as biochemistry are an integral part of many sciences including animal (veterinary science), human health science and many parts of environmental science. We have many experienced tutors who are qualified to teach introductory biochemistry. Depending upon your particular interest in biochemistry we will assign a tutor in the appropriate field at enrollment.
