[Campbell Biology P.572] Which of the following statements accurately describes a key differ... | Practice Question

Which of the following statements accurately describes a key difference between allopatric and sympatric speciation as presented in the text?

  • option_A: Allopatric speciation involves geographic separation, while sympatric speciation occurs without it.
  • option_B: Sympatric speciation always results from polyploidy, whereas allopatric speciation never does.
  • option_C: Gene flow is reduced in sympatric speciation due to habitat shifts, but not in allopatric speciation.
  • option_D: Allopatric speciation typically occurs much faster than sympatric speciation.

Explanation

The text clearly states: 'In allopatric speciation, gene flow is reduced when two populations of one species become geographically separated...' and 'In sympatric speciation, a new species originates while remaining in the same geographic area as the parent species.'
