A Major Difference Between Allopatric and Sympatric Speciation Is Whether

Multiple Choice

A major difference between allopatric and sympatric speciation is whether

A) the resulting species are reproductively isolated or not.
B) gene flow continues to occur or not.
C) two or three species result.
D) geographic isolation is required or not.
E) the new species are separated by a prezygotic or postzygotic isolating mechanism. The prefix allo- means "different," whereas the prefix sym- means "same." The root word of both terms, patria, loosely means "homeland." Thus, the two types of speciation are differentiated by whether or not geographical isolation is required-allopatric meaning "different homeland," and sympatric meaning "same homeland."
