How do mammals offspring are produced?

Answer 1

Reproduction is animals having offspring. In mammals, this involves sexual reproduction, wherein a male fertilizes the egg of a female, which harbors the new young mammals as embryos. In most mammals, the young are born after much development as placental fetuses, and then are nursed. In marsupials, the young are born at a lower level of development, and continue to grow while nursing in a pouch. In monotremes, or egg-laying mammals, the embryo develops outside the female in an egg, then is nursed after hatching.
