    Sympatric speciation is when there is no physical barrier to separate the two populations, but when their gene pools deviate from one another through behavioural/reproductive isolation mechanisms (e.g. different mating routine, incompatible sex organs, different mating times etc) so that gene flow is restricted.

    Allopatric speciation is when there is a physical barrier so that geographical isolation occurs - for example, either side of a mountain range. This means that the two separated populations are subject to different selection pressures, so that their gene pools gradually diverge until they can no longer interbreed, even when they meet again.

    Hope that helps.
