  1. 1The Biological Species concept emphasizes....
    1. AReproductive Isolation
    2. BGenetic Variations in populations
  2. 2What is Speciation ?
    1. AIt explains the differences and similarities between species
    2. BIt blocks fertilization
  3. 3The Biological species concept:
    1. ASpecies in a population or group have the potential to interbreed in nature and produce viable offspring, but they can't produce babies with other populations
    2. BCan interbreed with whoever they want regardless of species
  4. 4Reproductive Barriers are split into two categories: 1) Prezygotic and 2) postzygotic, what are they consisting of?
    1. APre: prevent attempting mate, successful completion of mating, hinder fertilization if mating is successful, and post: reduced hybrid viability and or fertility
    2. BNo such thing
  5. 5Prezygotic Barriers consist of 4 different isolation techniques
    1. ATrue
    2. BFalse
  6. 6Post-Zygotic Barriers consist of three barriers, including:
    1. A1) Gametic Isolation fertilization
      2) Reduced Hybrid Fertility
      3) Hybrid Breakdown - visible in fertile offspring
    2. Bthere are only two
      Gamete Isolation and fertilization
  7. 7Speciation can take place with or without geographic separation.
    1. ATrue
    2. BFalse
  8. 8What is Allopatric Speciation?
    1. AGeographic Isolation restricts gene flow between the populations
      i.e. squirrels in the grand canyon
    2. BReproductive barriers can isolate a subset of a population w/o geographic separation
      i.e. geographically overlapping populations
  9. 9What is Sympatric Speciation?
    1. AReproductive barriers can isolate a subset of a population w/o geographic separation
      i.e. geographically overlapping populations
    2. BGeographical isolation restricting gene flow
  10. 10Can [sexual selection] breeding coloration affect whether two species breed together?
    1. ATrue
    2. BFalse
