This activity introduces a number of different ways that genetic tests can be used in medicine.
It uses real-life scenarios to explore the many reasons why someone would seek or be offered a genetic test. Students are given a scenario and use problem solving to choose the features of an appropriate genetic test. Students then role play a genetic counselling appointment.
The activity also introduces some of the social and ethical implications of genetic testing.
A full teacher guide is available for this activity. It includes further information and examples of current tests for each of the scenarios. Teachers can email firstname.lastname@example.org from a school email address to gain access.
HSC Biology NSW
- investigate the use of technologies to determine inheritance patterns in a population using, for example:
- DNA sequencing and profiling
- evaluate the benefits of using genetic technologies in agricultural, medical and industrial applications
- interpret a range of secondary sources to assess the influence of social, economic and cultural contexts on a range of biotechnologies.
Causes and Responses (Non-infectious Diseases)
- investigate the causes and effects of non-infectious diseases in humans, including but not limited to:
- genetic diseases
- investigate the treatment/management, and possible future directions for further research, of a non-infectious disease using an example from one of the non-infectious diseases categories listed above
Inheritance and associated terminology (allele, genome, multifactorial, genotype, homozygous/heterozygous, dominant/recessive, carrier)
Punnett squares for predicting risk to offspring
Variants, SNPs (could be introduced during the lesson)
Technology- PCR, microarray, sequencing (could be introduced during lesson, resource links provided)
