Fruit Flies and frog eggs are long-time,well characterized standbys in the lab environment,and specific manipulations allow researches to introduce genes from other organisms into these species

From the mother's body, - they are inside it while they are embryos.
The One with the Embryos was created on 1998-01-15.
All chordates embryos have pharngeal slits.
Embryos are protected by the physical structures of the reproductive system, such as the uterus in mammals. Embryos are protected by the presence of amniotic fluid or egg membranes that surround and cushion the developing embryo. Embryos are protected by parental care, such as brooding behaviors in birds or the provision of nutrients and a safe environment in mammals.
The early embryos of all animals have a very similar appearance. This is no different for chicken and pig embryos.
what is the source of nourishment for developing fish embryos?

Embryos are frozed in liquid nitrogen through a process called cryofreezing. Embryos are generally frozen to be stored for long periods of time or if they have to be trasported to a different location.
Is it true that you can only have 2 embryos transferred in the US? We were looking to have three with the thought of having twins or triplets intentionally. No, it is not true. A good reproductive endocrinologist will transfer as many that can be SAFELY transferred. A good one would never implant more than two, if he feels sure all three could possibly take (with high grade embryos). Also it is depends on healthyness of body. If the body is not capable to keep those embryos to long term period then it is not posible.
