Prinsip dasar reproduksi hewan
In most fish and amphibia (frogs and toads) fertilisation of the egg cells takes place outside the body. The female lays the eggs and then the male deposits his sperm on or at least near them.
In reptilesand birds, eggs are fertilized inside the body when the male deposits the sperm inside the egg duct of the female. The egg is then surrounded by a resistant shell, “laid” by the female and the embryo completes its development inside the egg.
In mammals the sperm are placed in the body of the female and the eggs are fertilized internally → develop inside the body of the female → born → milk excreted from the mammary glands and protected by their parents
The reproductive organs of mammals produce the gametes (sperm and egg cells), help them fertilise and then support the developing embryo.
