  1. 3. the process of random fluctuation in allele frequencies due to sampling effects
  2. 6. a technique used by evolutionary biologists to approximate the time two species diverged (hint: 2 words, no space)
  3. 7. also known as silent mutations, this type of substitution results in a change in nucleotide sequence that doesn't affect the amino acid (protein) sequence
  4. 10. a form of natural selection that selects for an advantageous trait/mutation in a population
  5. 11. the ________ neutral theory of evolution takes into account the deleterious and advantageous mutations at the molecular level
Down
  1. 1. the evolutionary theory which says that many amino acid and nucleotide substitutions have little or no functional consequence and thus aren't strongly constrained by natural selection.
  2. 2. a mutation where a purine is exchanged for another purine or a pyrimidine for another pyrimidine; a synonymous ________
  3. 4. a type of substitution that results in the changing of the nucleotide sequence, which in turn changes the amino acid (protein) sequence
  4. 5. a mutation where a purine is exchanged for pyrimidine or vice versa; a synonymous ____________
  5. 8. this form of natural selection selects against an advantageous trait/mutation in a population
