Embryology Exam: Ultimate Trivia Quiz! - Quiz

Embryology is the biology branch that focuses on the prenatal development of gametes, fertilization, and embryos and fetuses. This quiz is centered on when the developing human is called embryo, where fertilization occurs, what causes variations in human species, cell division, where does implementation occur, and from where do cells come. Take this quiz and see how much you know about embryology.
