Research Report: Genetic Technology and Population Genetics

Task Description

Applications of genetic technology are increasingly important in twenty-first century agricultural, medical, and industry practices. DNA sequencing is becoming an affordable tool researchers and medical practitioners can use.

Investigate one of the following claims:

• Gene therapy can reverse ageing

• There is a relationship between ethnicity and prevalence of mutated genes

• DNA testing can prove genealogical ancestry

• Transgenic organisms offer a viable and effective future for human health

• Artificial manipulation of DNA has the ability to change populations forever

• Sustainable reserve size should be based on the data from gene pool variability

With teacher approval, you may investigate a different claim related to the knowledge and content outcomes.

Tasks:

1. Conduct initial background research around one of the possible claims to develop a research question.

2. Gather secondary evidence related to your research question in order to evaluate the claim.

3. Obtain evidence by researching scientifically credible sources, such as scientific journals, books by well-credentialed scientists, and websites of governments, universities, independent research bodies, or science and technology manufacturers. You must adhere to research conventions.

Your report should include in-text citations and a reference list according to school guidelines. It is expected that you will use current and peer-reviewed sources for your research. PubMed contains a number of free articles; in addition, there are many articles and databases to explore when you log in through the National Library.

Step 3: Background Research

• Mentor advised consulting chapters 6–9 of Biology in Focus and credible scientific journals.

• The student summarized DNA structure, mechanisms of inheritance, and relevant genetic technologies.

Step 4: Evidence Collection

• Mentor recommended selecting 5–6 credible sources, analysing trends, patterns, and limitations.
