Genetics is Changing the World!
 
It is changing how we think about the world around us.
 
Genetics is important in many areas, such as plant science, animal science, nutrition, psychology, child behaviour and much more.
 
An understanding of genetics will be more important as we move into the future, but it can be a difficult subject to understand if you don't have a proper grasp of the fundamentals.  Grasping those fundamentals is what this course is about!
 
Learn about cellular function, traits, characteristics and heritability.
 
This is how living organisms become what they are, how we differ from one another and from other species.
 
Studying genetics can feel like studying another language – the biological language of genes and DNA. It is expected that you will have some prior biological study to undertake this course.
 
Our knowledge of genetics changes daily. This course will provide you with a foundation to enable you to understand more about genetics and review new studies and information as they come to learn. Learn more about this fast moving field NOW!

GENETICS TODAY
Everything from agriculture and horticulture, to veterinary and human health science, is being impacted increasingly by our rapidly developing understanding of genetics. While the future may not be predictable, there is little doubt that a knowledge of genetics will lay a very good foundation for many business and employment opportunities over the coming decades.

Consider the following.

Farm Animal Breeding
Selective breeding in farm animals is centred around identifying the most desirable characteristics and breeding from those animals that display them. Traits essentially fit into five basic categories:

1. Fitness traits: these are usually linked to reproduction such as litter size, conception rate, gestation length, survival rates of young.
2. Production traits: these include milk yield, growth rate, feed efficiency, number of eggs.
3. Quality traits: these include carcass composition, level of fat, meat and milk quality.
4. Type traits: these include physical appearance such as coat colour, udder shape, number of teats in pigs.
5. Behavioural traits: these include herding ability in sheep dogs, temperament, mothering ability.


Pet breeding
Whereas the main objective of a farm animal breeding program is to improve performance, breeding programs for pedigree cats and dogs and other pet animals has centred on how they look i.e. the phenotype. This has led to the development of over 1700 different dog breeds throughout the world. Pedigree dog breeding is big business and can generate significant amounts of money for the breeder. In recent years it has come under heavy criticism as one of the consequences of breeding for specific traits that effect appearance is that other genes may also be selected that are detrimental to the dogs health and welfare. In particular some breeds e.g. pugs and King Charles Spaniels were being breed with such shortened noses that they were having breathing problems


Plant Breeding
Plant breeding has been practiced for thousands of years, since near the beginning of human civilization. It is essentially the manipulation of plant species in order to create desired genotypes and phenotypes for specific purposes. These days, this manipulation involves either controlled pollination, genetic engineering, or both, followed by artificial selection of progeny.

Classical plant breeding uses the planned crossing of closely or distantly related individuals to produce new crop varieties or lines with desirable properties. These may include colour, shape, disease resistance or potential yield in crop producing plants. Plants are crossbred to introduce traits/genes from one variety or line into a new genetic background.

It is now practiced worldwide by government institutions and commercial enterprises as it is believed that breeding new crops is important for ensuring food security through the development of crops suitable for their environment such as drought conditions or warmer climates.


HUMAN HEALTH
Genetics research has lead to an understanding of what causes disease, the diagnosis of diseases and genetic screening to identify populations that are of risk from a specific genetic disorder.

Diagnosis of disease
Genetic testing is used to diagnose many disorders such as Turner’s syndrome, Klinefelter’s syndrome and many heart and blood disorders. The diagnosis of a genetic disorder may indicate that the relatives of the affected person should be screened for the genetic defect or whether they carry the gene.

Genetic Screening
This is the use of a test to identify people who have, are predisposed to or carriers of a certain genetic disease. It can be applied at many stages of life and used for a variety of purposes.

Genetic Engineering
Changing the structure of genes, may offer possibilities to manipulate human health benefits.
