It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth.en.wikipedia.org/wiki/GestationGestation is the carrying of an embryo or fetus inside a female viviparous animal, until its birth. Mammals can have more than one embryo or fetus at the same period. The time between fertilization of an ovum and the birth of the young is called the gestation period. Humans have a gestation period of around 37 weeks or about 9 months and 1 week.simple.wikipedia.org/wiki/GestationFor mammals, the gestation period is the time in which a fetus develops, beginning with fertilization and ending at birth. The duration of this period varies between species. For most species, the amount a fetus grows before birth determines the length of the gestation period.en.wikipedia.org/wiki/Pregnancy_(mammals)
