2. Which fertilization and development method is most typical of humans before birth occurs?

Humans are higher eukaryotic organisms, which give birth to live young. They show internal fertilization and internal development of fetus (inside the body of female). Fertilization takes place near the fallopian tube, present in the female body, during which male gamete (sperm) fuses with female gamete (egg) to form zygote. The zygote gets attached to the uterine wall, where it develops into embryo, and later on, into fetus. The fetus lives in uterus and gets nutrition from mother until birth. Thus, in humans, 'internal fertilization and internal development' are most typical methods before birth.
