What is the main message of the chapter Heredity and Evolution?

Answer and explanation

Correct answer: Traits pass through generations and variations can lead to evolution over time

The chapter connects two governing ideas: heredity and evolution. Heredity explains how genetic information and traits are transmitted from parents to offspring. Reproduction can also introduce heritable variations, so members of a population are not always identical. If useful variations are preserved over many generations by natural selection, populations may gradually change and evolve. Therefore option A gives the complete message, while the other options deny heredity, variation, or the role of inherited traits.
