Quizplus · Accepted Answer

In Xenopus embryos, the correct developmental sequence is cleavage, blastula, gastrula, and then neurula. Cleavage is the initial series of cell divisions, forming the blastula. Gastrulation follows, forming the three germ layers, and neurulation is the development of the nervous system.
