BIG IDEA
Advances in technology have
enabled the identification of genetic
relationships through the use of
genetic testing and tracing.
LEARNING FOCUS
• DNA sequencing can be used to screen for genetic disorders, tracking
individuals and identifying paternity. 65 - 71
• DNA can be used to identify species. 72 - 77
• Phylogenetic trees are diagrams that can be used to show the relatedness of
organisms. 78 - 79
• Tracking genes can be used to help explain our origins. 80 - 82
