The process of evolution that occurs when certain phenotypes confer an advantage or disadvantage in survival and/or reproductive success is called...Question 18Answera.standard evolutionb.genetic driftc.gene flow.d.natural selection.

Match the mechanism of natural selection with its corresponding description.the process by which individuals with advantageous traits have higher chances of survival and reproductionthe mechanism that allows genetic information to be passed down from parents to offspringthe period over which changes accumulate, leading to the emergence of new traits and the extinction of othersthe diverse range of traits exhibited among individuals within a populationthe outcome of natural selection, where populations become better adapted to their specific environmentsa.adaptationb.selectionc.timed.variatione.inheritance

Natural selection occurs whenMultiple Choicewhen a small number of individuals of a population break away and form a new population.a factor in the environment alters the genetic information in DNA of all members of a species.only when nonrandom mating occurs.a new genetic variation occurs that allows individuals to have a reproductive and survival advantage.
