c
Only traits that are controlled by genes can be acted on by natural selection. Genes play a crucial role in evolution as they determine the traits that are passed down from one generation to the next. Traits that are advantageous for survival and reproduction are more likely to be passed down to future generations, leading to changes in a population over time. Genes with favorable variations are more likely to be passed down, while genes with unfavorable variations are less likely to be passed down.
