Embryology the study of the development of a unicellular zygote into a complete, multicellular organism; in the course of nine months, a unicellular human zygote undergoes cell division, cellular differentiation, and morphogenesis in preparation for life outside teh uterus; much of what is known about mammalian development stems from the study of less complex organisms such as sea urchins and frogs Fertilization an egg can be fertilized within 12-24 hours after ovulation; fertilization ...
