5130623720	allopatric	speciation that results from a geographic barrier	18
5130623721	sympatric	speciation that happens without a geographic barrier	19
5130623722	mechanical isolation	type of sympatric speciation in which the mating structures are incompatible	20
5130623723	gamete isolation	type of sympatric speciation in which the gametes cannot fuse	21
