| What is a Hybrid?
Hybrid breeding on PI is when you breed two ponies of different breeds together, and the resulting baby is a third different breed. This resulting breed is considered a "hybridable breed", meaning it can be obtained by hybrid breeding.
The hybridable breeds on PI are the MerPony (Mer), WingedUnicorn (WU), MerDragon (MerD), and WishingPony (WP).
For the purpose of this tutorial even purebred/starter Mers, WUs, MerDs, and Wishies are considered hybridable, even if they themselves weren't born as a hybrid.
History of Hybrid Breeding
The ability to hybrid breed was introduced to PI on 3/13/06, the same day the WU was released. At this time an already existing breed, the Mer, was also made into a hybridable breed. (Prior to this, Mers bred and were bred like any other breed on PI). Later two more hybridable breeds, the MerD and the WP, were released on 3/13/09. |
07-30 00:05 Sokemis 4975 - USR | Breeding Hybrids to Other Breeds
Hybrid ponies don't "breed true" in the same way the non-hybridable ("regular") ponies do. When you breed a normal pony to a breed other than its own, you have a 50% chance of the baby being that breed.
Hybrid ponies breed a little different however. They, even purebreds of the hybridable breeds, "breakdown" and breed as if they were one of their parent breeds (see above post for the parent breeds of each hybrid). This means that if you bred a WU (even a starter WU) to a seapony, the resulting baby could be a seapony, pegasus, or unicorn - but not a WU.
Exceptions to the rule:
There are two exceptions to this rule:
1) MerDragons - MerDragons breakdown and breed as either merponies or dragons. If a MerD breeds as a Mer, it does not breakdown a second time to a seapony or earthie.
2) Merpony x Dragon - Because a mers/dragons pairing is able to produce MerDs, mers do not break down to sea or earthie when bred to dragons.
The breeds in a hybrid's (or any pony's) lineage has not affect on what breed babies it can have, or how likelyhood of said pony having a baby of a particular breed.
Results of Breedings Involving Hybrids
Below are the possible outcomes when breeding hybrids with the other breeds (and the probibility of each outcome).
Merpony
Mer x Mer = Mer (100%)
Mer x Dragon = Mer (40%), Dragon (40%), MerD (20%)
Mer x Sea = Sea (70%), Earth (20%), Mer (10%)
Mer x Earth = Earth (70%), Sea (20%), Mer (10%)
Mer x MerD = Mer (70%), Dragon (20%), MerD (10%)
Mer x Wishie = Sea (25%), Earth (25%), Uni (25%), Fairy (25%)
Mer x WU = Uni (25%), Peg (25%), Sea (25%), Earth (25%)
Mer x other = other (50%), Sea (25%), Earth (25%)
WingedUnicorn
WU x WU = WU (100%)
WU x Peg = Peg (70%), Uni (20%), WU (10%)
WU x Uni = Uni (70%), Peg (20%), WU (10%)
WU x Fairy = Fairy (45%), Peg (25%), Uni (20%), Wishie (10%)
WU x Wishie = Uni (45%), Peg (22.5%), Fairy (22.5%), WU (5%), Wishie (5%)
WU x Mer = Sea (25%), Earth (25%), Uni (25%), Peg (25%)
WU x MerD = Uni (25%), Peg (25%), Mer (25%), Dragon (25%)
WU x other = other (50%), Peg (25%), Uni (25%)
WishingPony
Wishie x Wishie = Wishie (100%)
Wishie x Uni = Uni (70%), Fairy (20%), Wishie (10%)
Wishie x Fairy = Fairy (70%), Uni (20%), Wishie (10%)
Wishie x Peg = Peg (45%), Fairy (25%), Uni (20%), WU (10%)
Wishie x WU = Uni (45%), Fairy (22.5%), Peg (22.5%), Wishie (5%), WU (5%)
Wishie x Mer = Sea (25%), Earth (25%), Uni (25%), Fairy (25%)
Wishie x MerD = Uni (25%), Fairy (25%), Mer (25%), Dragon (25%)
Wishie x other = other (50%), Uni (25%), Fairy (25%)
MerDragon
MerD x MerD = MerD (100%)
MerD x Mer = Mer (70%), Dragon (20%), MerD (10%)
MerD x Dragon = Dragon (70%), Mer (20%), MerD (10%)
MerD x WU = Uni (25%), Peg (25%), Dragon (25%), Mer (25%)
MerD x Wishie = Mer (25%), Dragon (25%), Uni (25%), Fairy (25%)
MerD x other = other (50%), Mer (25%), Dragon (25%)
Explination of When Hybrids Breed True
You'll notice that in some cases a hybridable breed has a baby that is the same breed as itself or even a different hybridable breed. This is due to the way hybrids breakdown to their parent breeds.
- Say you breed a Wishie to a peg. There's a 50% chance the wishie will breed as a uni. If it does, there's a chance of getting a hybrid WU baby (it would be like breeding a uni to a peg)
- Now say you breed a WU to a Wishie. There's a 50% chance the WU will breed as a uni. There's also a seperate 50% the Wishies will breed as a fairy. If this happens, there's a chance of getting a hybrid Wishie baby (it would be as if you had bred a uni to a fairy).
There's also a 50% chance the WU will breed as a peg, and a seperate 50% chance the wishie will breed as a uni. If this happens, there's a chance of getting a hybrid WU baby (it would be as if you had bred a peg to a uni).
A hybridable breed, when bred to its own breed, will always have a baby of that breed. |
