At the end of meiosis do all cells go through differentiation

No, not all cells go through differentiation at the end of meiosis. Differentiation is the process by which cells become specialized and take on specific functions in the body. In meiosis, germ cells (sperm and egg cells) are produced, and these cells do not undergo differentiation immediately after meiosis. Instead, they undergo further development and maturation before they become fully differentiated and ready to fulfill their specific roles in reproduction. Other non-germ cells that are produced in meiosis, such as polar bodies, typically do not undergo further differentiation and are eventually discarded.
