Process

• What is step 1 of natural selection?


  Random mutations result in new alleles of a gene
• What is step 2 of natural selection?

  Many mutations are harmful but in certain environments, the new allele of a gene might benefit its possessor = increased reproductive success
• What is step 3 of natural selection?

  The advantageous allele is inherited by members of the next generation
• What is the 4th and final step of natural selection?

  As a result, over many generations, the new allele increases in frequency within the population
