An adaptation must be inheritable in order to be passed down from one generation to the next. If an adaptation is not inheritable, it will not be maintained in the population over time through natural selection, and therefore will not lead to evolution. Inheritability ensures that the adaptive trait can increase in frequency within a population over generations.
Recessive genes are replaced by dominant genes over time and unfavorable genes die out.
