Explain how an organism's phenotype is influenced by the interaction between its genome and its environment.
Describe variation within a population as arising from genetic inheritance, environmental conditions, or a combination of both.
Acknowledge the extensive genetic variation that naturally exists within biological populations.
Explain that all genetic variants originate from continuous mutations, noting that most have no phenotypic effect, some influence it slightly, and very few dictate it entirely.
Understand that a rare, beneficial mutation can create a new phenotype that, if advantageous for survival, leads to rapid species adaptation.
