'''Egg groups''' determine which Pokémon are able to interbreed in [[Pokémon breeding]]. [[Pokémon]] were first able to breed in the [[Generation II|Second Generation]] games [[Pokémon Gold and Silver]]. [[Breeding]] allowed Pokémon to pass down [[DVs]] and moves to their children. Moves usually are inherited from the male Pokémon, while the child takes on the form of the mother in her basic form. A baby would hatch out of an egg after a specified number of steps in the game and would always be at level five.
{{EggGroups}}
'''Egg Groups''' (Japanese: '''タマゴグループ''' ''Egg Group'') are categories which determine which {{OBP|Pokémon|species}} are able to [[Pokémon breeding|interbreed]]. The concept was introduced in [[Generation II]], along with breeding. Similar to [[type]]s, a Pokémon may belong to either one or two Egg Groups.


When breeding, one typically has a 50/50 chance of getting male or female Pokémon. If the Pokémon is a [[Starter Pokémon]], or any of a number of other types which have different gender ratios than 50-50, the results are skewed.  Some Pokémon are genderless; some species can be only male or only female. It's been mentioned on some web sites that there is a bug in the [[Generation III|Third Generation]] games which makes some {{p|Azurill}}s change gender when they evolve into {{p|Marill}}s. This is the result of the fact that the gender ratios are different.
==Overview==
Egg Groups are based on biological traits of [[Pokémon (species)|Pokémon species]], generally allowing biologically similar species to breed. However, there are some oddities within Egg Groups: for example, the {{egg2|Field}} contains a particularly wide variety of Pokémon species, so that seemingly illogical pairings can be noted within it, such as {{p|Skitty}} and {{p|Wailord}}.


Egg Groups are generally preserved along [[List of Pokémon by evolution family|evolutionary lines]]; however, [[baby Pokémon]], {{p|Nidorina}}, {{p|Nidoqueen}}, and {{p|Shedinja}} are not in the same group as their evolutionary relatives: baby Pokémon, Nidorina and Nidoqueen are in the {{egg2|No Eggs Discovered}} and thus unable to breed, while {{p|Shedinja}} is in the {{egg2|Mineral}} (although it requires {{p|Ditto}} to breed due to being a [[Gender unknown|gender-unknown]] Pokémon).


=Breeding Chains=
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.
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.


[[TM]]s are also passed down through breeding through male Pokémon. Doing this would cause the moves to appear in the Pokémon's moveset if said Pokémon can learn the move via TM or [[Egg Moves|Egg Move]].
==Breeding chains==
Many Pokémon are included in two different Egg Groups and can form what are known as [[chain breeding|breeding chains]]. These link many unrelated Pokémon together, allowing moves that would not normally be accessible to certain Pokémon to be legal, like {{m|Heal Bell}} on {{p|Blissey}}.


=Egg Groups=
[[TM]]s are also passed down through breeding from the [[gender|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.
== Ditto ==
Ditto can breed with any Pokémon except for [[Legendary Pokémon]]. However, Ditto can also breed with What is known as Gender unkown Pokémon.


=== Gender unknown ===
=== Connections ===
The following genderless Pokémon may only breed with Ditto.
The groups {{egg|Ditto}} and {{egg|No Eggs Discovered}} are unique in terms of connectivity, the first one allows breeding with any other group and the second one does not allow breeding with any Pokémon, not within this group nor with Ditto.


*[[Shedinja]]
In the Generation II, when the Egg Groups were introduced, most of the remaining groups were connected and could allow crossbreeding and passing down moves to other groups with exception of {{egg|Amorphous}}, {{egg|Mineral}} and {{egg|Human-Like}}. All three groups were connected starting from Generation III.

=Special Notes=
Other important facts about breeding:
<br>
Azurill and Wynaut can be bred only by giving the father(/mother?) a Sea or Lax Incense to hold. (respectively)
<br>
Pichu will acquire {{m|Volt Tackle}} if the father(/mother?) is holding a Light Ball, but only in [[Pokémon Emerald]].

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.

Overview

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 Field Group contains a particularly wide variety of Pokémon species, so that seemingly illogical pairings can be noted within it, such as Skitty and 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 No Eggs Discovered Group and thus unable to breed, while Shedinja is in the Mineral Group (although it requires Ditto to breed due to being a gender-unknown Pokémon).

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.

Connections

The groups Ditto and No Eggs Discovered are unique in terms of connectivity, the first one allows breeding with any other group and the second one does not allow breeding with any Pokémon, not within this group nor with Ditto.

In the Generation II, when the Egg Groups were introduced, most of the remaining groups were connected and could allow crossbreeding and passing down moves to other groups with exception of Amorphous, Mineral and Human-Like. All three groups were connected starting from Generation III.

The number indicates the generation in which two Egg Groups were directly connected through a Pokémon.

Egg Groups

This is a list of Egg Groups by their index number in the games:

  1. Monster Group: Pokémon in this group are saurian/kaiju-like in appearance and nature.
  2. Water 1 Group: Pokémon in this group are amphibious in nature.
  3. Bug Group: Pokémon in this group are insectoid (bug-like) in appearance.
  4. Flying Group: Pokémon in this group are avian (birdlike) in appearance.
  5. Field Group: The largest group, Pokémon here are terrestrial in nature. In Stadium 2, this Egg Group was known as "Ground".
  6. Fairy Group: Pokémon in this group are petite and considered very cute.
  7. Grass Group: Pokémon in this group are plantlike in appearance. In Stadium 2, this Egg Group was known as "Plant".
  8. Human-Like Group: Pokémon in this group are fully bipedal. In Stadium 2, this Egg Group was known as "Humanshape".
  9. Water 3 Group: Pokémon in this group resemble aquatic invertebrates.
  10. Mineral Group: Pokémon in this group are inorganic in nature.
  11. Amorphous Group: Pokémon in this group are amorphous, having no definite form. In Stadium 2, this Egg Group was known as "Indeterminate".
  12. Water 2 Group: Pokémon in this group are piscine (fishlike) in appearance.
  13. Ditto Group: As the name implies, Ditto is the only Pokémon in this group, and is capable of breeding with all other Pokémon (regardless of gender) aside from those in the No Eggs Discovered and Ditto groups.
  14. Dragon Group: Pokémon in this group are draconic in appearance.
  15. No Eggs Discovered Group: Pokémon in this group are unable to breed. In Stadium 2, this Egg Group was known as "No eggs".
