GENETICS GRADE 9 MYP 4  UNIT 1 - HOW DO CHARACTERISTICS PASS FROM ONE GENERATION TO ANOTHER? Statement of Inquiry Saturday 4 January 202 Evidence shows that our identity and 5 relationships with other people are determined Global Context by both the patterns in our genetics and our Identities and Relationships environments. Global context exploration: Human nature Related concepts Key concept ATL Skills – Social Skills Patterns Evidence RELATIONSHIPS Communication Skills: Give and receive meaningful feedback Inquiry question: Factual: What are the roles of DNA, genes, and chromosomes in the inheritance of traits? Conceptual: How do dominant and recessive alleles interact to determine the traits expressed in an organism? Debatable: To what extent should humans intervene in genetic inheritance through practices like genetic modification or selective breeding? Learning Objective: Analyze the mechanism of inheritance of genetic traits.
