1The Biological Species concept emphasizes....
- AReproductive Isolation
- BGenetic Variations in populations
2What is Speciation ?
- AIt explains the differences and similarities between species
- BIt blocks fertilization
3The Biological species concept:
- 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
- BCan interbreed with whoever they want regardless of species
4Reproductive Barriers are split into two categories: 1) Prezygotic and 2) postzygotic, what are they consisting of?
- APre: prevent attempting mate, successful completion of mating, hinder fertilization if mating is successful, and post: reduced hybrid viability and or fertility
- BNo such thing
5Prezygotic Barriers consist of 4 different isolation techniques
- AVerdadero
- BFalso
6Post-Zygotic Barriers consist of three barriers, including:
- A1) Gametic Isolation fertilization
2) Reduced Hybrid Fertility
3) Hybrid Breakdown - visible in fertile offspring - Bthere are only two
Gamete Isolation and fertilization
- A1) Gametic Isolation fertilization
7Speciation can take place with or without geographic separation.
- AVerdadero
- BFalso
8What is Allopatric Speciation?
- AGeographic Isolation restricts gene flow between the populations
i.e. squirrels in the grand canyon - BReproductive barriers can isolate a subset of a population w/o geographic separation
i.e. geographically overlapping populations
- AGeographic Isolation restricts gene flow between the populations
9What is Sympatric Speciation?
- AReproductive barriers can isolate a subset of a population w/o geographic separation
i.e. geographically overlapping populations - BGeographical isolation restricting gene flow
- AReproductive barriers can isolate a subset of a population w/o geographic separation
10Can [sexual selection] breeding coloration affect whether two species breed together?
- AVerdadero
- BFalso
11What is polyploidy?
- Aextra set of gametes
- BExtra Set of chromosomes
12Hybrid Zones reveal...
- Afactors that cause reproductive isolation
- Bsexual selection
13Hybrids are the result of mating between species with incomplete reproductive barriers
- AVerdadero
- BFalso
