Genetics is Changing how we Think and Work!
 
in health science  -  in agriculture  -in horticulture    ...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!

Genetics is being used increasingly by all sorts of people, in all sorts of jobs -not just plant scientists; and that trend is set to continue.

It is likely that an understanding of genetics will become increasingly important for people who work on farms, in plant nurseries, zoos, veterinary practices, medical offices and many other places You might not need to be a geneticist; but you are likely to need the level of knowledge imparted in this course.

 

Studying genetics can feel like studying another language – the biological language of genes and DNAIt is expected that you will have some prior biological study to undertake this course.
 

Lesson Structure

There are 10 lessons in this course:

  1. Introduction to Genetics
  2. The Cell and Organelles
  3. Interaction between Chromosomes
  4. Interaction between Genes
  5. Genetic Chemistry (DNA and Chromosomes)
  6. Mutations (Genomes and Mutations)
  7. DNA repair and Recombination
  8. Developmental Genetics
  9. Population Genetics
  10. Applied Genetics

Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.

Aims

  • 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.
  • Develop knowledge of biological interactions and understand the significance of gene expression in heritability.
  • Describe chemicals and chemical reactions that are involved with genetics
  • 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.

THE FUTURE OF GENETICS
 
All life sciences, from agriculture and horticulture, to veterinary and human health science, are 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.

Farm Animal Breeding
Selective breeding in farm animals is centered 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 centered 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.
 

 

Learn the fundamentals

Whether it is important for you to understand why organisms look the way they do and how they work; or whether you want to learn the genetic principles that underpin so many disciplines so that you can apply your knowledge; or whether you are contemplating a career involving genetics and are wanting to start out with the basics... A knowledge of the fundamental genetic concepts is invaluable... and this course will teach you just that.
