Monozygotic polyembryony is a form of asexual reproduction that proceeds by division or budding during post-zygotic or early embryonic stages of the life history (Hughes ).Only monozygotic polyembryony occurs in animals, whereas in certain higher plants, especially among angiosperms, a second form of ‘polyembryony’ involves somatic embryogenesis and perhaps Cited by:.
