👉 Hyperodontogenesis is a type of gastrulation in which a developing embryo develops from two different cell types, each with its own differentiation and growth pattern. This process occurs during the zygote stage of embryonic development, where the blastocyst undergoes meiosis, leading to the formation of two genetically distinct cells: an oocyte (a female germ cell) and a sperm cell (a male germ cell). The oocyte is then fertilized by the sperm, resulting in a diploid
