BMEN 515 Lecture Notes - Sympatric Speciation, Hybrid Zone, Reproductive Isolation

Allopatric speciation requires almost complete genetic isolation • Speciation that results when a populations is divided by a physical barrier. • Is thought to be the dominant mode of speciation among most groups...
