Breeding in Pokémon GO

Related Articles

Pokémon GO Breeding is still not released, however, we created this page to help understand the breeding mechanics from other Pokémon Games and how it works.

There is a lot of confusion about how Breeding worked in the core games, especially in the Egg groups section, so let’s clarify that. This page will be updated with Breeding info once Breeding becomes a thing in Pokémon GO.

Breeding Rules in Pokémon GO

The basics of breeding in Pokémon GO are probably going to be the same as in other Pokémon games. Here we go:

  • You need two Pokemon from the same egg group, if they match in one of their egg groups they will produce an egg.
  • IVs are passed down from the parents to the child
  • The egg produced will be the same species as the mother.E.g A Male Ekans breeding with a Female Dratini makes a Dratini egg (50/50 chance of the egg hatched being Male or Female). This does not mean non viable Females are useless just breed until a Male is hatched with the same IVs (every Pokemon has a gender ratio, so make sure you check it, Chansey for example is 100% Female so you will never hatch a Male Chansey).
  • Males are able to pass down moves to the egg.
  • Pokemon that do not have genders cannot breed (except with Ditto)
  • Ditto can breed with every Pokémon

How Egg Groups work

Alola Egg Groups (click for high res)

Breeding in Pokemon, and probably in Pokémon GO also, is done through egg groups and is not limited to the same species, as shown by the “Alola Egg groups” image.

There are two things that get passed down with trading:

  1. Moves
  2. IV values

In other words, a 100% Gyarados (even with Bite and Twister) may actually become a very valuable breeding tool, as the Magikarp family belongs to two egg groups: Dragon egg group and the Water 2 egg group.

    • I’ll try to explain how it works.
      1. In generations I and II (of the main series) the way IV worked was different so I’m gonna say how it works in newer games.
      2. There’s a big difference between Pokemon stats in Pokemon Go and in other games. Here every Pokemon has less stats and only three IV: attack, defence and stamina. In normal Pokemon games (in third generation and later) there are six IVs: attack, defence, special attack, special defence, speed, hp. In first two generations there were 4 IVs…
      3. When you simply breed Pokemon, their kids inherit 3 random IVs (each from random parent) out of 6. If you give parents certain items to hold before breeding, you can make the kids inherit an IV you choose (for example Power Anklet makes it get speed IV from a parent holding it) and there’s one item called Destiny Knot that makes them inherit 5 IVs instead of 3. Some hardcore players use such tricks to breed perfect or nearly perfect Pokemon, most don’t care too much about it.
      4. Aside for generation I, the shininess can’t be passed to the offspring but there are some tricks that make the kids more likely to be shiny (still – in generation 6 with a special item and method the best chance you can get is 1/512).

      I hope it was helpful or at least not very boring.
