Gestation is the carrying of an embryo or fetus inside a female viviparous animal. In mammals that undergo a pregnancy, they can have one or more gestations at the same time, resulting in multiple gestations. In the case of multiple gestations, the organisms gestated by the mother are called twins.
For example, female dogs usually have multiple ovulations in a single estrus cycle, and, when the ova get fertilized, the animal gestates multiple offspring in one single pregnancy.
The time interval of a gestation is called a gestation period and the length of time they have spent developing in the uterus is the gestational age.
