Year 12 Genetic Cross Workshop
This workshop is offered at the School of Botany each Tuesday across term 3. It is designed to complement the curriculum in VCE Biology Unit 4 and is based on ‘real-life science’.
THERE IS NO CHARGE FOR THIS WORKSHOP
The science:
We work with the model plant Arabidopsis thaliana. The use of model organisms in research is discussed.
After a brief revision of the parts of a flower, students are introduced to the idea of homeotic genes and the role they play in development, with particular reference to flower development.
Mendelian genetics is recapped, although it is assumed that students have at least a basic understanding of Mendelian inheritance prior to the session.
The ABC model of flower development is discussed, as well as the phenotypic effects of mutations in these floral genes.
In the practical work, students examine a mono-hybrid cross between plants heterozygous for the agamous mutation in Arabidopsis. This mutation is in one of the genes involved in flower formation. Dissecting microscopes are used to examine the flowers of the offspring. Class data is pooled and a 3:1 ratio is expected.
The workshop:
- PowerPoint introduction to the science
- Hands-on activities in small groups
- Worksheets completed during the workshop
- Assessment materials suitable for a SAC provided to teacher
- Workshop approximately 1 hour 45 minutes in length
- Limit of 30 students per session
- Session start times set to suit schools’ needs as far as possible
Bookings:
We have one lab available every Tuesday. Bookings are taken on a first-come basis. A single class can complete this workshop and the DNA manipulation workshop on the one day. Where concurrent sessions are requested, we will do our best to accommodate, but cannot guarantee lab space will be available.
For further information or to make a booking, contact Marie Thorpe on 8344 5071 or email thorpem@unimelb.edu.au.
A risk assessment for this workshop is available on request.
