Which option gives the deepest correct conclusion of the whole chapter?
Answer and explanation
Correct answer: Genetic information forms traits, variation gives a basis for selection, and evolution occurs over long periods
The chapter connects heredity, variation, natural selection and evolution. Genes carried on chromosomes transmit information that helps produce traits. Mutations and recombination can create variation, and heritable differences may affect survival and reproduction. Over many generations, the accumulation of such population-level changes can produce evolution. Therefore A gives the complete conclusion; B confuses acquired traits with inherited traits, while C denies essential requirements and D is biologically incorrect.
