👉 Zymogenesis is a process in which cells divide into two daughter cells, each with an identical set of chromosomes. This process is essential for the development of multicellular organisms such as humans and animals. In zymogenesis, the cell cycle begins at the end of meiosis I. The first meiotic stage (prophase) involves the replication of DNA, which results in four sister chromatids being separated into two separate cells. These daughter cells undergo a series of changes, including cytokinesis and
