No. Fishes fertilize externally.
All of them. If fertilization did not take place the species would not exist. If you mean gender...then the female.
Whale has internal fertilization,because they are mammals like human. ^_^
All birds, chickens included, are fertilised internally. Both the male and female birds have a cloaca. And it is through their cloaca that sperm is passed. An example of external fertilisation is the frog, the male emitting sperm onto the spawn that the female is releasing.
Like all mammals, elephants employ internal fertilisation.
All birds fertilize their eggs internally. A male bird has to mate with a female in order for a fertilized egg to be produced.
They breed like any other mammal with the male covering and fertilizing the female, but instead of live young the female lays a single egg in a pouch.
Fertilisation in kangaroos is an internal process, not external. This is the case with all mammals.
It does nothing at all. If you take it internally you will be going to the ER.
All reptiles fertilize internally
Because - external fertilisation is 'left to chance'. There's no guarantee that every egg laid will be fertilised by sperm. Internal fertilisation is much more successful.
Fertilization in cats typically occurs inside the female's body in the oviducts during mating. The female's eggs are fertilized by the male's sperm within the reproductive tract.
All mammals use internal fertilization.
