POKEMON BREEDING GUIDE
Breeding in the Advance Generations is pretty much the same as breeding in Gold, Silver and Crystal, but there are a few changes. So let's find out how to breed in Ruby, Sapphire & Emerald, and FireRed & LeafGreen!
If you are playing Pokemon Ruby, Sapphire or Emerald, the Breeding Center can be found on Route 117.

If you are playing Pokemon FireRed or LeafGreen, the Breeding Center can be found on Island #4.

You will need to give your Pokemon to the Lady inside. As in GSC, you need two compatible Pokemon. Firstly, you need a male and a female with one egg group in common (Check the Pokedex). After a certain number of steps an egg will be produced - this is dependant on the trainer numbers and the Pokemon species. After even more steps it will finally hatch. It will be level 5 and it will be in the same family as the FEMALE pokemon, in the lowest evolutionary stage. There are four exceptions to this:
- A baby hatched from a Nidoran F's egg will be either Nidoran M or Nidoran F.
- A baby hatched from an Illumise's egg will be either Illumise or Volbeat.
- A baby hatched from an Azumarill's or Marill's egg will usually be Marill. See below for more details.
- A baby hatched from a Wobbuffet's egg will usually be Wobbuffet. See below for more details.
While the two Pokemon are in the daycare, you can check on the chances of getting an egg. Talk to the old man outside and he will tell you one of four things:
- "They seem to get along very well" There is a 70% chance of producing an egg.
- "They seem to get along" There is a 50% chance of producing an egg.
- "They don't seem to like each other" There is a 20% chance of producing an egg.
- "They prefer to play with other Pokemon than each other" There is a 0% chance of producing an egg.
The trigger for getting your egg occurs every 256 steps, so after you have taken that many steps, check back to the daycare center to see if an egg has been produced.
Breeding two Marills or Azumarills will produce a Marill.
Similarly breeding two Wobbuffets will produce more Wobbuffets!
In order to produce an Azurill, one of the parents must be holding Sea Incense
Similarly, in order to get Wynaut, one of the parents must be holding Lax Incense 
Here is a table of the egg groups for all Pokemon. Alternatively, check out the Pokedex.

There are three different ways a baby can obtain an ability. Firstly, set abilities. If it belongs to a family that always has only one ability, then the baby will also have this ability. Secondly, if it belongs to a family that has two abilities, then the baby's ability is random. Thirdly, if it belongs to a Pokemon family which changes abilities as it evolves, it will simply change its ability at each evolutionary stage to what is normal in that family. The baby will not obtain its mother's ability if the mother is evolved and it would not normally have the ability.
Attacks obtained by the baby uses the same principles as in GSC.
- The baby knows all moves it normally has from levels 1-5.
- If both parents know a move by levelling up, and the baby is able to learn the move by LEVELLING UP, NOT evolving, then the baby will be born knowing this move.
- If the father knows a move the baby can learn by TM then the baby will be born with this move.
- If the father knows one of the baby's egg moves, then the baby will be born with the move.
When an egg is produced, a nature is chosen at random for it. This is for stat modification. For more information on natures check out the Natures Guide.
Different Pokemon require a different number of steps to hatch. Below is a table showing how many steps is required to hatch each Pokemon.
