Mekanisme isolasi reproduktif atau penghalang hibridisasi adalah kumpulan mekanisme, perilaku dan proses fisiologis yang mencegah anggota dari dua spesies yang berbeda yang disilangkan atau kawin dari menghasilkan keturunan, atau yang memastikan bahwa setiap anak yang mungkin dihasilkan steril. Hambatan ini menjaga integritas spesies dari waktu ke waktu, mengurangi atau langsung menghambat aliran gen antara individu dari spesies yang berbeda, yang memungkinkan konservasi karakteristik masing-masing spesies.[1][2][3][4]

a. ^ The DNA of the mitochondria and chloroplasts is inherited from the maternal line, i.e. all the progeny derived from a particular cross possess the same cytoplasm (and genetic factors located in it) as the female progenitor. This is because the zygote possesses the same cytoplasm as the ovule, although its nucleus comes equally from the father and the mother.[3]
