And in Gen 4 both parents must be from the same language game.

Pokmon can learn new moves through breeding, and furthermore some Pokmon are only obtainable with this method.

If two compatible Pokmon are left with the daycare lady, they will produce an egg.

The games are purposely vague about how this happens.) Pokmon are compatible for breeding if.

The Pokmon that hatches will be the same species as the female, but at the bottom of the evolutionary chain.

For example, breeding a female Blastoise with a compatible Pokmon would generate a Squirtle egg.

In the case of Ditto, the Pokmon egg will always be the non-Ditto Pokmon - so if you breed Ditto with a male Charizard, the egg would be a Charmander.

For example, breeding a male Golduck with Nidoran would yield either Nidoran or Nidoran.

When a particular Incense is held, the offspring will be a baby Pokmon, otherwise it will be the next stage up in the evolutionary line.

For example, breeding a female Roserade will produce a Roselia egg, but if the Roserade is holding a Rose Incense, it will produce a Budew egg.

For each of them the result is a Phione egg, but Phione does not evolve into Manaphy.

If the male Pokmon knows moves that the baby Pokmon is capable of learning, the baby will know them when it hatches from the egg.

Prior to Generation 5 this was a good way to reuse TMs that you taught a Pokmon and cannot re-obtain (TMs are no longer passed down by breeding).

If both parents know a move that the child would learn by level up, the child will also know it upon hatching.

For example, breeding two Ampharos knowing Thunder will deliver a Mareep knowing Thunder at level 1.

Furthermore, there are some moves Pokmon can only learn by breeding - these are called egg moves, and are listed in our Pokdex alongside the other moves.

In most cases, another Pokmon in the same egg group learns the move by level up and can pass it on by breeding, but sometimes you need to chain breed from one Pokmon to another to another.

In practice, this means that if the parent has a regular ability, there is an 80 chance the child has the same ability slot (60 20) and 20 chance it has the other slot.

For hidden abilities, the child has a 60 chance of having its hidden ability and 20 chance for each of its regular abilities (or 40 if it only has one regular ability).

For example, Poochyena has the abilities Run Away or Quick Feet, while Mightyena has Intimidate or Quick Feet.

A Poochyena bred from a Mightyena with Intimidate has an 80 chance of having Run Away and 20 chance of Quick Feet.

If the Mightyena has Quick Feet, Poochyena has an 80 chance of Quick Feet and 20 chance of Run Away.

In Gen 5, only females could pass down abilities; males bred with Ditto reverted to the 5050 chance for each ability.

Normally the nature is chosen at random from the 25 possibilities, but as natures raise and lower certain stats, often you will want a specific nature.

So if a Pokmon is holding the Everstone item, its child is guaranteed to have the same nature.

If both parents hold an Everstone the nature is chosen at random between the two.).
