modes are distinguished from viviparity, which covers all the modes that result in live birth: Histotrophic viviparity: the zygotes develop in the female's...

first two of these modes were categorized under histotroph viviparity, or aplacental viviparity. The young of ovoviviparous amphibians are sometimes born...

vipers exhibit ovoviviparity. The more developed form of viviparity is called placental viviparity; mammals are the best example, but it has also evolved...

Adenotrophic viviparity means "gland fed, live birth". This is the reproductive mode of insects such as tsetse flies (Glossinidae), keds (Hippoboscidae)...

young are nourished by egg yolk. There are two types of viviparity in fish. In histotrophic viviparity, the zygotes develop in the female's oviducts, but she...

In plants, vivipary occurs when seeds or embryos begin to develop before they detach from the parent. Plants such as some Iridaceae and Agavoideae grow...
