Genetics is set to change the way we go about horticulture over the coming decades; and an understanding of this area of science may well be critical to being able to take advantage of developments in the industry and get the jump on your competitors in the future.

An understanding of genetics is increasingly important but it can be a difficult subject to understand if you do not have a proper grasp of the fundamentals. Grasping those fundamentals is what this course is about! Genetics is an expansive field that branches into all areas of biology. It explains how living organisms become what they are, how they differ from one another, and how they differ from other species. In this course you will learn about cellular function, traits, characteristics and heritability.

When you understand genetics, you have a foundation for understanding how new plant cultivars are created.  It is the genetic processes that cause desired characteristics to emerge in a plant. If you want plants that resist disease, produce better flowers; bear larger crops; produce tastier fruit or grow in harsher climates; you need to understand genetics. This is the first step toward achieving such outcomes.

This course cannot teach all there is to know in this vast subject area; however, with this course as a foundation, you are better placed to understand what you encounter, and continue your learning over the years that follow.

Aims

  • Discuss the history of genetics.
  • Explain terminology used in genetics, particularly relevant to study of plant and animal sciences, conservation of plant and animal species, agriculture, horticulture, veterinary medicine and human health sciences.
  • Understand the structures (organelles) of cells and comprehend their basic functions specifically relating to cell division.
  • Discuss the main ways features are inherited.
  • Discuss biological interactions and the significance of gene expression in heritability.
  • Describe chemical reactions involved in genetics.
  • Explain the nature and management of genetic mutations.
  • Explain 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 endeavours.


The Future - How Will A Knowledge Of Genetics Aid Your Career?

Genetics is set to be of huge significant in all areas of agriculture, horticulture, health and animal sciences over the coming decades.

If you want a career or business in any of these industries, a knowledge of fundamental genetics is likely to be at the very least important, and more likely, absolutely essential: 

  • Farmers who understand genetics will understand how to better manage crops and livestock.
  • Health practitioners who understand genetics will better understand how to care for their patients 
  • Environmental managers who better understand genetics will better understand the environments and the species they are working with.

The Next Step

This is a solid foundation course covering the basic principles and applications of genetics. It is sure to provide you with a sound knowledge of basic genetics applicable to a variety of disciplines and underpinning many biological processes.
