Formation of morula

WebThe cleaving Xenopus egg first forms a morula; this is followed by the blastula stage (Fig. 46-1). Signals from the vegetal hemisphere cells act on the overlying equatorial cells to induce the formation of mesoderm. 1–3 Following this, there is a marked change in gene expression causing maternal and paternal information to be generated. A ... WebThe early stages of embryonic development, such as fertilization, cleavage, blastula formation, gastrulation, and neurulation, are crucial for ensuring the fitness of the organism. Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm each contain one set of chromosomes.
