  1. 3. a mutation where a purine is exchanged for another purine or a pyrimidine for another pyrimidine; a synonymous ________
  2. 5. the evolutionary theory which states that variation in a population is mostly due to neutral mutations
  3. 6. also known as silent mutations, this type of substitution results in a change in nucleotide sequence that doesn't affect the amino acid sequence
  4. 9. a technique used by evolutionary biologists to approximate the time two species diverged (hint: 2 words, no space)

  1. 1. the process of random fluctuation in allele frequencies due to sampling effects
  2. 2. this form of natural selection selects against a trait/mutation in a population

  4. 4. Professor Smith has an impressive one of these
  5. 7. a type of substitution that results in the changing of the nucleotide sequence, which changes the amino acid sequence
  6. 8. a form of natural selection that selects for a trait/mutation in a population
