A Major Difference Between Allopatric and Sympatric Speciation Is Whether

question 50

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."
