- Which of the following is NOT true while comparing internal to external fertilization. In external fertilization, zygotic DNA replication starts after the fusion of gamete pronuclei; in internal fertilization, the first zygotic DNA synthesis happens before pronuclei fusion. B Capacitation is only observed in internal fertilization. In both internal and external fertilization, the cortical granule reaction is required for the slow block to polyspermy. In external fertilization, intracellular calcium release is stimulated prior to gametes fusion; in internal fertilization, it happens after gametes fusion. In both internal and external fertilization, there is a slow and a fast block to polyspermy.List and explain the steps used in embryo transfer.Compare and contrast the mechanisms of polyspermy block in internal versus external fertilization.
