# Breed Apostles can breed. Parents combine their genes and pass along to their children with mutations that affect their physical appearances and talents. The [population](/getting-started/game-entities/apostle/population.md) is increased through this way. ## Biological Parents Breeding requires two Apostles to work together. We support the regular way of breeding at the moment, but we may experiment with some radical scenarios. ### Genders * Male + Female = Success * Male + Male = Fail * Female + Female = Fail We are thinking about allowing MM or FF breeding in the future. It will unlock a hidden trait with a "Rainbow Tatoo" on the body. But this breeding will cost higher (a special surgical procedure required), and the rate of death is high. ### Species On the Atlantis continent, all Apostles are human alike, while on the Byzantine continent, they look like an alien. They belong to two different species. Inter-species mating is not allowed. ### Close Relatives This is a big NO. Brothers and sisters, immediate family members, can not breed. ## Cool Down Time Every Apostle knows that making babies is hard work. As a result, your Apostle needs time to rest after it breeds. This is called the cooldown. The more kids an Apostle has, the longer it needs to rest between breedings. An Apostle is born with a cooldown speed determined solely by the Apostle's generation number; genetics have nothing to do with it. The lower the Apostle's generation, the faster its initial cooldown. Every time the Apostle breeds, its cooldown period lasts longer. To sum up: * Cooldown is not based on traits. It’s based solely on an Apostle's generation. * Lower generation Apostles are always born with faster cooldown speeds. * Every time an Apostle breeds, its cooldown period increases. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
