  1. 2. a type of substitution that results in the changing of the nucleotide sequence, which changes the amino acid sequence
  2. 6. a mutation where a purine is exchanged for pyrimidine or vice versa; a synonymous ____________
  3. 8. the process of random fluctuation in allele frequencies due to sampling effects
  4. 9. greatest EEB390 GSI ever

  1. 1. a technique used by evolutionary biologists to approximate the time two species diverged (hint: 2 words, no space)
  2. 3. the ________ neutral theory of evolution provides a relationship between population size and the rate of molecular evolution
  3. 4. Professor Smith has an impressive one of these
  4. 5. a form of natural selection that selects for a trait/mutation in a population
  5. 7. also known as silent mutations, this type of substitution results in a change in nucleotide sequence that doesn't affect the amino acid sequence
  6. 10. the evolutionary theory which states that variation in a population is mostly due to neutral mutations
  7. 12. this form of natural selection selects against a trait/mutation in a population
