Which statement gives the most correct balance between heredity and variation?
Answer and explanation
Correct answer: Heredity maintains similarity and variation provides new differences
Heredity is the transmission of genetic information from parents to offspring, so it produces resemblance and continuity between generations. Variation refers to differences among offspring or individuals; it supplies the raw material on which natural selection can act. The two ideas work together: heredity preserves successful patterns, while variation introduces differences that may improve adaptation. Therefore option A gives the correct balance, unlike the absolute claims in the other options.
