All cells in an embryo have the same heredity, yet they develop into different tissues and organs and organ systems. What is the process by which this happens?

Dear student
The process of formation of different tissues, organ and organ system from the same DNA of the cell in an embryo is called cellular differentiation. This process of cellular differentiation is controlled by epigenetics where modification of DNA sequence leads to controlled expression of gene in embryo for the formation of different tissues, organs and organ system.
