Discussion Section Guidelines:
Discussion section for exercise 1 and 2. For each separate discussion section, organize according to
the following subheadings.
Succinct statement
• The first sentence is a succinct statement that answers the research question for that section.
• Always mention the species name.
Chi-square test conclusion
• Explain/state the chi-square test end result/conclusion.
• Refer to the table number.
• Explain further what this means as related to the research question.
Final concluding explanation
• State the function of the gene product.
• Explain the importance of the gene product to that species.
• Are there potential consequences of mutations (substitutions) in the non-synonymous region of
the gene sequence for that species (i.e. is this gene important to conserve for this species, why or
why not).
• Include citations throughout your discussion from the relevant article or textbook
Discussion section for rates of substitutions.
• The first sentence is a succinct statement that answers the research question.
• Always mention the species name.
• Compare the textbook information with each of your results for the rates of substitutions.
• Consider especially the graphs in section 7.3 “Silent sites …” from your textbook.
• Refer to the table number.
• Include citations throughout your discussion from the textbook
R coding in RStudio
• Review the instructions set out in the IN-lab exercise document on Brightspace.
• Repeat the same steps but altering the observed and expected information to correspond with
the two chi-square tests for the rbcL gene and the Tas1r2 gene.
• After you have run your chi-square tests in RStudio, copy your work from the Console and
paste it into your assignment.
Writing – a small proportion of marks will be given for good writing.
In text Citations and End References Refer to Knisely (2017) on pages 89-101
• Use the Canadian Science Editors (CSE) Name-Year (N-Y) System (Knisely (2017).
• Include in text citations and end references from the article posted on Brightspace, any secondary
sources such as textbooks but the lab manual should not be used as a reference.
