What are the three categories of natural selection depending on the favored traits? a.Directive, selective and native b.Indicative, normative and fixative c.Directional, stabilizing and…
What is true about evolution by natural selection? a. It is a largely random process. b. Homology shows that convergence is a useful tool for deducing adaptive function. c. Mothers are invariably members of the same species as their offspring, so selection can never create new species. d. Harmful recessive genes are eliminated more rapidly than harmful dominant genes. e. None of the above is true.
