What is the deepest scientific conclusion of the whole chapter?
Answer and explanation
Correct answer: Genes control traits variation gives the basis for selection and evolution occurs across generations
The chapter connects heredity, variation, and evolution into one scientific framework. Genes carry hereditary information and influence traits, while variations create differences among individuals. Natural selection or other evolutionary processes can change the frequency of such inherited differences over many generations. Thus option A correctly combines the essential ideas. Option B confuses acquired changes with inherited traits, option C removes the necessary basis of evolution, and option D gives an incorrect general explanation of sex determination.
