Alicorn ponies can be naturally born in any family, though they are very rare. They can’t do everything a real alicorn can do, however. They either can’t use their magic or they can’t fly. That is because of the genetic defects. In such alicorn’s DNA it is written that they are either a pegasus or a unicorn despite them having both wings and a horn.

There are cases, however, when an alicorn is able to use both wings and the horn. It is a very, very rare case though, that happens once in a few centuries.

Unicorns have never had any problems with same-sex reproduction. Thanks to their ability to control magic with their horns, they are able to overcome biological barriers. That means that any pony who is in a relationship with a unicorn is able to have offspring regardless of their gender and species.
