The male inserts his 'gonopodium' into the females 'cloaca' and releases his milt (sperm). Her 'ova' (eggs) are then fertilised internally.
Guppies are livebearers. So they don't lay eggs. Male guppies WILL eat their own baby guppies. They will eat any baby guppy they see. It doesn't matter if it's their own or some other guppies'. Male and female guppies eat baby guppies.
Male guppies chase pregnant female guppies because they are trying to mate with them and fertilize their eggs. This behavior is natural for guppies and is a part of their reproductive process.
yes the female fighter has eggs before she meets the male, when they meet and do there business the female will release her eggs and the male will fertilise the eggs
No, the platypus does not fertilise its eggs externally.
All roosters crow. But the crowing IS NOT what fertilizes the eggs. They are fertilized when the male mates with the female.
guppies
No. A male Betta is needed to spawn out the female and fertilise her eggs.
A male guppy will fertilise any female guppy it is in with. Mother,sister, no relation, whatever. It doesn't know and it doesn't care. That is nature.
No they don't get pregnant. A female produces eggs, then during mating a male will squeeze those eggs out of the female and fertilise them. The eggs are then put in a bubble nest by the male who cares for them until they hatch.
It depends on the fish. Most fish are egglayers, where the female lays the eggs and the male fertilizes them externally. Fish like mollies, guppies and platys are livebearers, where the male internally fertilizes the eggs and the female gives live birth. Fish like chilids are mouthbrooders, where they keep the eggs in their mouths until they hatch, and protect their young by using their mouths. Gouramis make bubble nests, laying their eggs in a nest of bubbles at the surface of the water. There are many ways fish mate, it just depends on the fish.
eggs to fertilise and sperm to fertilise it
yes or separate them with a screen of plastic not zinc or aluminum at least or the male will eat the eggs
