reproductive isolation a Habitat isolation geographic barrier prevents contact b Temporal isolation reproduce at different time of dayyear c Behavioral isolation important in mate choice d Mechanical isolation size in genitalia prevents mating e Gametic isolation gametes fail to unite 229 Brie y explain the three Postzygotic barriers that block the development of fertile individuals a Hybrid inviability fertilized egg can t progress past early embryo b Hybrid sterility interspecies hybrid viable but sterile c Hybrid breakdown hybrids viable and fertile but subsequent generations have
