👉 In biology, idiogenesis is a process by which new cells develop from an existing cell. It occurs during development in eukaryotic organisms and involves the formation of a new nucleus, mitosis, and cytokinesis (the final stage of cell division). The end result is a single, genetically distinct cell that can differentiate into multiple different cell types. Idiogenesis is a crucial process for maintaining the continuity of an organism's genetic material throughout its development.
