Detailed explanation-1: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’
Detailed explanation-2: -Which of the following resulted from a genetic variation that was favored by natural selection? Peppered moths use the adaptation of camouflage as protection from predators.
Detailed explanation-3: -Natural selection requires variation between individuals. Mutations and sexual reproduction increase genetic variation in a population.
Detailed explanation-4: -Which of the following examples of natural selection in action would tend to increase the genetic variation in the population? Natural selection causes dragonflies to evolve longer tails.
Detailed explanation-5: -Diversifying or disruptive selection increases genetic variance when natural selection selects for two or more extreme phenotypes that each have specific advantages.
