Transmission of heritable characteristics from one generation to the next involves DNA and genes (ACSSU184)

Elaborations
  • describing the role of DNA as the blueprint for controlling the characteristics of organisms
  • using models and diagrams to represent the relationship between DNA, genes and chromosomes
  • recognising that genetic information passed on to offspring is from both parents by meiosis and fertilisation
  • representing patterns of inheritance of a simple dominant/recessive characteristic through generations of a family
  • predicting simple ratios of offspring genotypes and phenotypes in crosses involving dominant/recessive gene pairs or in genes that are sex-linked
  • describing mutations as changes in DNA or chromosomes and outlining the factors that contribute to causing mutations

Drugs may contain a 'biological calling card'

Illegal drug producers may leave behind DNA in the drugs they manufacture. This 'biological calling card' can then be used to locate and identify suspects. Find out how a South Australian scientist was able to extract DNA from a sample of drugs seized from a police drug-trafficking operation. Discover the new technique ...

Breast cancer: genes and inheritance

Discover an Australian woman's family history of breast cancer and the role of genes and inheritance in determining her own risk of developing breast cancer. Find out what she did to get off the breast cancer 'roller coaster'. Watch this clip to learn about the science behind the breast cancer risk and treatment of Angelina ...

'Junk DNA' not junk after all

Geneticists have long thought that 98 per cent of human DNA was 'junk' (or 'non-coding') DNA. However, recent scientific research suggests that there is much more to this DNA than first thought. Watch this clip to discover more.

Could you make a unicorn by crossing DNA?

Good question! Find out whether this is possible by watching as biologist at MIT, Dr Sera Thornton explains. What is a genome? And why do genomes need to be decoded? If the rhino genome was successfully decoded and the part that described the rhino horn was isolated, what would the process be for creating a unicorn?

New plants from old?

This is a unit of work for teachers that uses plant breeding to explain the basics of genetics. Particular concepts covered include: the principles of dominant and recessive genes; plant breeding using these principles; the scientist Gregor Mendel, who first recognised the principles; and the intellectual property (IP) ...

Researchers find grain's memory gene

This brief ABC News in Science article from 2009 gives an excellent example of responses of plants to temperature change and current Australian science. Plants use a genetic memory to recognise when it is spring and can even count the number of cold days.

GM Bananas

This 8 minute video segment from Catalyst explains how genetically modified bananas could be the answer to malnutrition in developing countries. Botanists in Queensland are developing genetically modified bananas that can boost vitamin and mineral content and create disease resistant varieties. Issues of lack of genetic ...

Cloning stem cells

Cell cloning involves making an exact copy of a cell. Geneticists have discovered that cell cloning can be used to create large numbers of stem cells. Stem-cell therapy holds much hope for the treatment of some of our most debilitating genetic diseases. Watch this clip to learn more about this exciting breakthrough and ...

Evolution and heredity: student guide

This is a student guide that takes an in-depth look at evolution and heredity. It begins and ends with students arguing their stances on contentious topics concerning evolution and genetics. The chapters on evolution provide the evidence for evolution and show how species chance. The section of heredity introduces the history ...

Who funds GM research trials?

Genetically modified (GM) foods are expensive to develop. They are often created through research partnerships between publicly funded scientists and private corporations. This offers advantages but also raises concerns about research objectivity and potential bias. Explore some of the issues surrounding the commercialisation ...

Meiosis

This is an interactive resource about how meiosis and fertilization shuffle the alleles that offspring inherit. Students explore meiosis with a computer model of breeding dragons. They run a simulation of the process of meiosis, inspect the chromosomes, then choose gametes to fertilize. They can then predict the results ...
