The zygote is the initial stage in baby development. Foetus refers to the final stage in baby development. An embryo is termed as the foetus at the beginning of the 11th week of pregnancy. A zygote is a fertilized egg formed by the fusion of the sperm and the egg.
What is difference between oviparity and ovoviviparity?
The key difference between oviparity ovoviviparity and viviparity is that oviparity is the trait of laying eggs, while ovoviviparity is the development of embryos inside eggs that are retained within the mother’s body until they are ready to hatch, and viviparity is giving birth to young ones directly.
What is ovoviviparous condition?

What is the different between oviparity and?
Oviparity is the mode of reproduction in which animals lay eggs, and the embryos develop externally. Ovoviviparity is another mode of reproduction in which animals lay eggs and develop the eggs inside the mother’s body. Viviparity, on the other hand, refers to giving birth to young ones directly.
What are the characteristics of ovoviviparity?
Ovoviviparous animals are similar to viviparous species in which there is internal fertilization and the young are born alive, but differ in that there is no placental connection and the unborn young are nourished by egg yolk; the mother’s body does provide gas exchange.
