Egg Group

Template:EggGroups

**Egg Groups** (Japanese: **タマゴグループ** *Egg Group*) are categories which determine which Pokémon are able to interbreed. The concept was introduced in Generation II, along with breeding. Similar to types, a Pokémon may belong to either one or two Egg Groups.

Egg Groups are based on biological traits of Pokémon species, generally allowing biologically similar species to breed. However, there are some oddities within Egg Groups: for example, the Template:Egg2 contains a particularly wide variety of Pokémon species, so that seemingly illogical pairings can be noted within it, such as Skitty Template:Appendix Wailord.

Egg Groups are generally preserved along evolutionary lines; however, baby Pokémon, Nidorina, Nidoqueen, and Shedinja are not in the same group as their evolutionary relatives: Baby Pokémon, Nidorina and Nidoqueen are in the Template:Egg2 and thus unable to breed, while the genderless Shedinja is in the Template:Egg2 (although it requires Ditto to breed due to being genderless).

Egg Groups are not displayed in any core series game; however, they have been canonically mentioned in Pokémon Stadium 2 as a part of Earl Dervish's Pokémon Academy's extensive data banks, in Pokédex 3D, and in various strategy guides.

## Breeding chains

Many Pokémon are included in two different Egg Groups and can form what are known as breeding chains. These link many unrelated Pokémon together, allowing moves that would not normally be accessible to certain Pokémon to be legal, like Heal Bell on Blissey.

TMs are also passed down through breeding from the father. Any move in the father's current moveset that can be learned via TM, Egg Move, or Move Tutor (in Crystal) will be passed down to the Pokémon hatching from the Egg.
