 UNIT 5 - WHAT FACTORS AFFECT HUMAN HEALTH? Statement of Inquiry The transmission of genetic traits across 01/09/2025 generations reflects patterns of inheritance, which can be modeled and analyzed using Global Context tools like Punnett squares to predict probabilities and understand the complexity of Identities and Relationships genetic diversity. Related concepts Key concept ATL Skills – Critical Thinking Patterns, Evidence Relationships Analysing genetic problems to predict inheritance patterns using Punnett squares. Inquiry question: Factual: What are the roles of DNA, genes, and chromosomes in the inheritance of traits?
