Question 18
The graph shows the increase in the global yield of wheat from 1800–2020. Genetically modified organisms (GMOs) are not currently used to grow wheat commercially. W... show full transcript
Worked Solution & Example Answer:The graph shows the increase in the global yield of wheat from 1800–2020 - HSC - SSCE Biology - Question 18 - 2023 - Paper 1
Step 1
What row in the table correctly identifies biotechnologies that have contributed to the increase in wheat yields and could be adapted to enhance commercial production in the future?
Answer
The correct row that identifies the biotechnologies contributing to the increase in wheat yields is option D:
D. Selective breeding
Hybridisation
This reflects the historical use of selective breeding and hybridization techniques, which have been essential in improving crop yields. In the present and future context, integration of methods like CRISPR for genetic modifications supports the enhancement of commercial production, while traditional practices remain relevant.
